The border cuts you in two.

PLOT SUMMARY:

When you immigrate, you leave a copy of yourself behind, an instance. One person enters their new country; the other stays trapped at home.

Some instances keep in touch, call each other daily, keep their lives and minds in sync in the hopes of reintegrating and resuming a life as one person. Others, like Soyoung Rose Kang, leave home at ten years old and never speak to their other selves again. Rose, in America, never imagined going back to Korea until her grandfather died and her Korean instance called her home for the funeral.

She doesn’t know that Soyoung plans to steal her body and her life.

How far would you go to live the choice you didn’t make?

GRADE: A

REVIEW:

Sublimation is equal parts tech thriller and diaspora story, set in a fascinating world where emigration creates two versions of a person: one remains in their country of origin while another begins life in their new home. It’s a bold, thought-provoking premise that immediately drew me in, and the excellent audiobook narration made the story even more immersive.

At the heart of the novel are the two versions of Soyoung Rose, each living a life the other envies. Watching them grapple with their separate identities, desires, and regrets was compelling. When they ultimately choose to merge into a single self, they discover that becoming whole comes with consequences neither could have anticipated. Their lives—and their understanding of who they are—can never return to what they once were.

This is the kind of complex science fiction that’s difficult to summarize but deeply rewarding to experience. Beyond its inventive technology, Sublimation explores questions of identity, belonging, and the different versions of ourselves that emerge from the choices we make. As someone who is both Italian and American, I found its exploration of dual identities especially resonant.

I highly recommend this book to readers who enjoy thoughtful science fiction that blends cutting-edge ideas with emotional depth. If you’re looking for a story that combines futuristic technology with a heavy dose of soul, Sublimation is well worth your time.
