From New York Times bestselling author Cynthia Hand comes a stunning, heart-wrenching novel of love and loss, which ALA Booklist called "both shatteringly painful and bright with life and hope" in a starred review.

Since her brother, Tyler, committed suicide, Lex has been trying to keep her grief locked away, and to forget about what happened that night. But as she starts putting her life, her family, and her friendships back together, Lex is haunted by a secret she hasn't told anyone--a text Tyler sent, that could have changed everything.
