Seventeen-year-old Cassie Morgan lives with a time bomb, a.k.a. her stepfather, Dino Cavalli. To the public, Dino is a world-renowned violin player and composer. To Cassie, he's an erratic, self-centered bully. And he's getting worse. Dino no longer sleeps, and he grows increasingly paranoid. Before, Cassie was angry. Now she is afraid.

Enter Ian Waters: a brilliant young violinist, and Dino's first-ever student. The minute Cassie lays eyes on Ian she knows she's doomed to fall head-over-heels in love with him.

Cassie thought she understood that love could bring pain, but this union will have consequences she could not have imagined.
