Genesis has loved her best friend for as long as she can remember-but now her feelings are poisoning her from the inside, blooming into blue-violet Lisianthus petals in her chest. Every cough is a reminder that love, unspoken, can be deadly. Caught between Caleb's unexpected jealousy, a mysterious new student who awakens desires she didn't know she had, and the impossible choice of her future, Genesis must confront a truth she can no longer deny: some hearts won't wait-and some flowers won't stop growing.
