Description
On the Island, where seals play in the shallows and the ptarmigan struts on the moor, a takeover bid is underway to sweep away a culture. Can the Islanders resist?
A world like, and unlike, eleventh-century Britain. An island like, and unlike, the Western Isles. Caerpadraig, the only town on the Island with a woman for their priest. And John Finlay, unsuspecting time-traveller, whom the Islanders call Dhion.
The town’s headman—the shareg—feels his age and must retire. The contest to replace him is intense and even the foreigner, Dhion, is drawn in. But, unknown to Caerpadraig, the Archpriest’s men are on the move, poised to spark the conflict that will change everything.
Bookended by a body washed up on a northern beach and a shared tot of whisky on the Inverness train, A G Rivett’s thoughtful speculative fiction draws on historical tensions between Celtic tradition and the mainstream Church. Implicit is a question—what would it be like to live more simply, more in harmony with the natural world?
Third book of A G Rivett’s visionary fiction. A novel in its own right.

Review excerpts from #Zooloosbooktour
Wonderful writing. A brilliant grasp of historical accuracy. A truly unique story. 5***** @Whatyoutolkienabout
This entire series has definitely made me think about how I want to live, and what kind of world we should be leaving to our children. One of my favourite series of all time. I'm going to be singing this books praises for a long time to come. @bluefairybugsbooks
A fantastic ending to a great fantasy series! I highly recommend this one to fans of the first two books of course, and also to people who love the human connections in stories, and fiction with a deeper meaning behind the words. 5***** @countrymamaswithkids
A poetic and spiritual ending to the trilogy. I think, after reading all three books, that they are the kind of reads that let you reflect on the depth in retrospect. Beyond the details of the surface information. @CherylM-M'sbookblog
This was such a great way to bring the series to a close. I could not put this one down. I devoured it over just three sittings. 5***** @book-a-holic-17
A powerful ending to the Trilogy. Each book had its own weight and prompted deep thoughts. The character development was done well and the plot was super interesting. The ebb and flow of dialogue and details kept me locked into this one (as well as the first two). I highly recommend this trilogy! At least add them to your TBR for now! @theoutsiderbookshelf
This was an incredible third and final installment to the Isle Fincara Trilogy. I fell in love with this series and it's characters and I will definitely re-read it in the future. @feistylittlereader
I was surprised how much I loved this series. It think it was mostly the setting I fell in love with: no phones, no technology, no stress. #SarahReads
A fascinating end to this trilogy, out of discord comes a new way that upholds the traditions but reshapes them for future generations. Dhion’s story comes full circle and the island disappears into the mist. @ramblingmads
The last book in this trilogy and I must admit I’m sad I’ve finished I’ve really enjoyed delving into this old world story. A great series. @lisa_reads_alot

Eileen Gonzalez for Foreword Clarion Review:
Though backdropped by battles, spiritual and moral concerns dominate life in A. G. Rivett’s immersive historical novel The Shareg.
Eleven years ago, Dhion tried to escape from his personal failures. He ended up being plucked from the contemporary world and deposited on a mythical island, Fincara. Though he settled into his new life, now, a fresh challenge awaits: The village chieftain has to step down, and Dhion is called upon to take his place during a tumultuous time. Facing threats from within the community and beyond it, Dhion, his family, and his allies fight to protect their lives and ways of living.
The villagers lead simple but satisfying lives in accordance with their particular religious traditions, which blend Christianity and paganism. The distant Archpriest is determined to bring their days in line with his own strict beliefs, though.
The story shifts between the perspectives of several key characters, including Dhion, as he makes the transition from village smith to community leader; his steadfast wife Shinane, who discovers the depths of her own strength when duty calls Dhion away; and Dhion’s adoptive mother, Morag. Morag’s position as unauthorized village priestess places her in the Archpriest’s sights, prompting a series of tense, high-stakes conversations about mindless obedience versus true faith, all while testing her resolve. These and the other inhabitants of Dhion’s village are varied and compelling, and well-chosen details illuminate their lives on Fincara, whose landscapes, like the surrounding sea, are rough yet beautiful.
The story is a grounded one. The idea that the strongest warriors are not those who wield a sword, but who are willing to take great risks for justice and truth, dominates. Attention is devoted to the villagers’ spiritual, moral, and emotional decisions and habits. Their personal concerns feed into a fitting, bittersweet conclusion that is overlaid with a sense of fatedness.
A series-concluding, contemplative historical novel, The Shareg is about a man elevated to a leadership position who seeks to balance tradition, tolerance, and progress in his adopted community.
Daniel Morphy for Pluscarden Benedictines:
In the final book of the Isle Fincara Trilogy, Dhion (formerly John Finlay) returns to centre stage with a strong supporting cast.
The plot centres on the clash of cultures which began in the previous volume when the Island’s Archpriest attempted, but failed, to convert the community of Caerpadraig from their Celtic style ‘God and Ghea’ cult of Christianity to something more orthodox. As Rivett explains in his Author’s Note, this echoes the historical transition between Celtic and Roman – not synonymous with Roman Catholic – Christianity, that took place in Britain over 1000 years ago. And Fincara’s troubles are far from over when the Archpriest proceeds to resolve the hiatus left over from the previous volume with all the tact and humanity of the KGB.
Christianity is not flagged up in any formal way, but the redeeming self-sacrifice of ‘the Chrisht,’ informs the actions and lives of the leading characters and thus the whole tone of the work. The book explores how uniting civil and religious power inevitably leads to forms of tyranny, something we have seen too much of in our own world. This leads to a gripping confrontation involving not only Dhion, but Caerpadraig’s ‘false’ priest Morag, the trainee Guardian Sorcha, the Guardians themselves and the island’s chiefs, the sharegs, whose authority the Archpriest has attempted to overthrow by instituting a ‘God-Shareg’ under his control. We follow the different characters in a number of intertwining sub-plots which resolve in a surprise ending that also seems inevitable, drawing full circle to the beginning of the first volume and setting the seal on the trilogy as a whole.
Notwithstanding the drama, a sense of peace inhabits this trilogy; a hope that providence will make things good in the long term, even for those who suffer and die. A fundamentally Christian view of things which we may preserve in some measure after we put the book down.

The Shareg, the eagerly anticipated third book in the Isle Fincara Trilogy, returns the reader to the remote island communities of Caerpadraig and Fisherhame and the medieval, mystical world of its particular form of Celtic Christianity. The opening chapter finds ‘the Seaborne’ of the first book a man of standing with a growing family—an Islander by adoption of some ten years. Originally fleeing a chaotic situation in modern-day London, he has come to value the simpler rhythms of the Island, and his former life seems ‘remote as a dream.’ When the ‘shareg,’ the community’s head man, stands down, he is even invited to put himself forward. All is going well when betrayal by a community member and the unexpected arrival of the Archpriest’s soldiers finds him on the run again, his life in danger of collapsing around him once more.
A central theme is that of power. There are many cloaks of power in The Shareg, either collaborating with, or standing against each other. The Archpriest’s mission to bring the Island to ‘the Perfection of Faith’ is little more than a clumsily disguised attempt to seize control. Through coercion and the imposition of a poisoned orthodoxy, his campaign endangers the soul of the island and is ‘deaf and blind to the value of anything beyond its narrow view.’ Against this stands the power of the shareg’s cloak, exercised in the serving and protection of the Island and its people; and with the sharegs, the spiritual power of the Guardians, a hidden circle of mystics and adepts. Finally, is the power to know oneself more deeply: the power of Becoming, which takes centre stage at the climax of the story.
In The Shareg Rivett has skilfully crafted an epic tale for modern times. A tale of love and betrayal, faith and doubt, cowardice and courage, battle and ultimate sacrifice. A multi-layered book that may be likened to a rich and beautiful medieval tapestry. The conclusion draws together all threads into a seamless and heart-warming whole. I simply love this book!

I'm back with the final review for The Isle Fincara Trilogy books and this is the third and final book in the series and oh my gosh, this was such a great way to bring the series to a close.
I've said before that this really isn't a genre that I read too often - and I've also said that whenever I step out of my comfort zone and read something different, I end up really surprising myself by loving the books.
This was certainly the case here and I think maybe because I've read all three books in quick succession - and therefore come to know all the characters and the community so, so well - I honestly think this book was the best of the three.
This was such an emotional read from start to finish and I literally could not put this one down.
I devoured it over just 3 sittings.
We continue the story from where we left it in book 2 - although set a few years on - and there's a definite sense of foreboding that we get from the prologues.
Having said this, I absolutely didn't see where this story was going to take us in the end.
Morag is now happily installed as the new priest, doing a great job, and life is good in the community of Caerpadraig - however, changes are afoot and due to their forward thinking, tough times are certainly heading their way.
As this is the final part of the whole Fincara story, I really don't want to say too much about the plot as there would definitely be many spoilers - but suffice to say that this whole book was a journey and there were so many things happened from start to finish.
I loved learning more about the Guardians and seeing the development of Sorcha's character.
Morag is caught up in the troubles and this was quite a moving final thread to her character storyline.
We also see a new challenge for Dhion and Shinane and the tying up of Dhion's story was in some ways as I'd expected, yet in other ways, I was completely unprepared for!
The conclusion to their stories is what had me riding that emotional rollercoaster to the final chapters.
Although I rated the first book a 4*, I think that the series as a whole is a 5* read for me and certainly one I'll be recommending in the future.
It's unlike anything I've read before and there are so many great elements to the story arc and so many great characters.
I think that the books could be read as individual reads and still make for an enjoyable experience, but for me, I'd absolutely read these in order and as a series.
The whole story arc and full character development is far more moving and meaningful if read in this way.
This series will be one that will stay with me for quite some time to come.

The third and final novel in A. G. Rivett’s Isle Fincara trilogy continues to delight with its vividly depicted landscape, so evocative of the Scottish isles, yet retaining the mystery of a world that exists beyond the boundaries of our own modern time and space. The rugged beauty of the setting is reflected in the simple lives of the island community, whose traditions and way of life are governed by the changing seasons. Here, reverence for the Earth exists alongside a Celtic Christian spirituality that is deeply woven into the life of the people.
The Shareg skilfully brings together the threads of the story developed through the earlier two novels. The narrative continues to centre on Dhion, an engineer from our own time who found himself washed up on the mysterious island; his wife Shinane; and Morag, whose position as the village Priest provokes outrage among the leaders of the new religion that threatens to extinguish the old ways of the island. The fate of these three characters becomes increasingly intertwined as the island itself is threatened by forces from beyond the sea that has, until now, protected it. Rivett handles these converging strands with a steady and skilful pace, allowing the story to build without losing sight of the rhythms of island life.
One of the themes I found particularly engaging is the novel’s exploration of where true spiritual power resides. It is not necessarily found in religious institutions that use physical force to implement their authority, nor in individuals driven by fervour and the desire for control (graphically illustrated in the character of the Archpriest) but in those who remain connected to the natural order of things. The simple, faithful life of the islanders increasingly comes into conflict with the religion of the empire, which seeks to bring their minds under its control but, in doing so, outrages their hearts.
This theme is particularly evident in the portrayal of the women of Fincara. Although the society is essentially feudal and men appear to hold the positions of authority, its women possess a strength that is easily overlooked because it is expressed through the ordinary roles of wives and mothers. As the story unfolds, however, these women increasingly come into their own with surprising results. When fate calls upon them, they prove more than equal to the task…
The Shareg is a story in the best tradition of storytelling. It has pace, tension and a satisfying denouement, while never abandoning the steady heartbeat of the small community at its centre. Most importantly, the final novel succeeds in drawing together the strands of the trilogy while remaining faithful to the distinctive atmosphere that has made the world of Fincara so compelling: a place where the boundaries between nature and spirit, past and present, brute force and the hidden power of nature converge. Despite its elusiveness, it is a world to which we as readers have been given rare and thoroughly enjoyable access.
