An incredibly fun and powerful work by one of my favorite writers. More people should be reading Jennifer Yu! I love how this is out-there and weird, but also grounded in very useful themes like family and friendship. Love the integration of electromagnetic interference. I am absolutely pre-ordering and teaching this in my YA course at Northeastern University. Highly recommend.

This book deals with death, grief and the impact these can have on others - directly and indirectly - and it deals with these SO WELL. It’s such an emotional read, it can be heartwarming one minute and then heartbreaking the next. The dynamics of the characters and the character progression was *chefs kiss*

The writing is so beautiful it had me staring off into space at times, I read this book in 24 hours as I just couldn’t put it down. I’d recommend this wholeheartedly but do check your trigger warnings beforehand especially if things like death do affect you

Thank you NetGalley for a free e-galley of this book in exchange for an honest review.

Jennifer Yu's "Grief in the Fourth Dimension" offers a fresh and thought-provoking take on young adult speculative fiction, weaving a poignant narrative about the afterlife, grief, and the enduring connections that transcend life and death. The novel's unique premise sets the stage for an exploration of loss and healing through the intertwined stories of Caroline Davison and Kenny Zhou, two high school classmates who, in life, were worlds apart but in death, find themselves sharing a surreal, timeless space.

Yu's portrayal of the afterlife is imaginative and emotionally resonant. The mysterious white room, which allows Caroline and Kenny to view their loved ones’ lives and influence events on Earth, serves as a powerful metaphor for the lingering presence of those we've lost. The novel brilliantly captures the complexity of grief and the process of coming to terms with one’s own death. It's rare to find a YA novel that handles such weighty themes with such grace and sensitivity.

The characters of Caroline and Kenny are richly developed, each bringing their unique backgrounds and struggles to the story. Caroline, with her passion for softball and a life marked by family dinners, contrasts sharply with Kenny, whose world was filled with NASA photo books and late-night shifts at his parents’ Chinese restaurant. Their evolving relationship in the afterlife, marked by mutual understanding and support, adds depth to the narrative.

However, the novel's speculative elements, while innovative, may not appeal to all readers. The concept of influencing the living world from the afterlife, through radio signals and psychic mediums, requires a suspension of disbelief that might not resonate with those looking for more grounded storytelling. Additionally, the pace of the novel is reflective and introspective, focusing more on character development and emotional journeys than on fast-paced plot twists.

Content warnings for themes of death and grief are appropriate, and the book will appeal most to readers who enjoy speculative fiction with a strong emotional core.

In conclusion, "Grief in the Fourth Dimension" by Jennifer Yu is a moving and beautifully crafted novel that offers a unique perspective on life, death, and the indelible impact we leave on those we love. It's a significant contribution to YA literature, particularly for those seeking a deep, reflective reading experience that explores the complexities of grief and healing.

I was just wondering where all the sci-fi YA was - and this book appeared on my radar!

It’s quirky and humorous, but also brutal and honest. The characters have dynamic and realistic personalities, and the writing is fantastic. This YA book deals with intense themes in an appropriate and approachable way, something that not all authors are able to do.

I loved the twists in the story, and they ALL took me by surprise and kept me on my toes!

Jennifer Yu wrote a fantastic story about the power of forgiveness and kindness in the face of incredible grief. Highly recommended!
