Twenty-nine-year-old Cassandra Green is running out of time.
A rare and devastating condition - Hanahaki disease - is causing a plant to bloom in her lungs, fed by the unrequited love she's never been able to let go of. The only cure is simple in theory but impossible in practice: confess her feelings to the woman she once hurt beyond repair ... or sever them completely. And Cass can do neither.Refusing surgery that would rip out not only the flowers but her very ability to feel, Cass abandons her life in England and flees to Japan, the birthplace of the mysterious affliction. Determined not to burden her friends, she plans to fade quietly into obscurity while searching for answers about the disease that will end her.
But fate has other ideas.
In a small corner of Tokyo, Cass meets the fiercely alive Ryo, who becomes fascinated by Cass' insistence on dying rather than confronting her past. As the girls grow closer, what began as an ending slowly starts to feel like the beginning of something Cass never believed she deserved.
In a journey woven with grief, healing, and the tender ache of second chances, Cass must choose: cling to a love that's killing her ... or embrace a future she never thought possible.
