Every book in the Boxer Boys series can be read on its own, but together the books form a world of diverse interlinked characters, like an organised crime version of Game of Thrones.

If you don’t know the Boxer Boys series, you should. If you do, then you know you’re in for a wild ride!

One ruthless kidnap. One crazy heist.

Sly Dolan, a key player in the infamous Boxer Boys gang that rides high in the underworld, is shocked when he receives a message — Your daughter has been taken.

For a start, Sly doesn't have any children, or so he thought. Then an ex-lover from his past emerges to insist the girl is real, the kidnapping is real, and the £20m ransom is way beyond her means. As a last-gasp measure Naomi Richards, now married to ex-met police officer Keith, has turned to the one man she believes could hold the answers.

The trouble is Sly has no control of the Boxer Boys purse strings so to save a daughter he never knew existed he comes up with a master plan. For it to succeed, though, he must betray his own family and trick his dying father Big Mo, who has been released from prison on compassionate grounds to see out his final days.

As he pursues his goal, every move will drag him deeper into a feud rooted in old gold, older grudges, and secrets buried since the bloody fallout of an infamous 80's bullion robbery. With time running out and enemies closing in, Sly must decide whether he is still the reckless joker everyone underestimates or the father Crystal needs him to become.

What he fails to realise is the kidnappers have a more sinister agenda – one that threatens to cost him everything.
