Tessa has just a few months to live.
Fighting back against hospital visits, endless tests and drugs with excruciating side-effects, Tessa compiles a list. It's her Before I Die list. And number one is sex. Starting tonight.
Released from the constraints of 'normal' life, Tessa tastes new experiences to make her feel alive while her failing body struggles to keep up. Her feelings, her relationships with her father and brother, her estranged mother, her best friend, and the powerful, bittersweet first love she finds with the boy next door - all are painfully yet beautifully crystallized in the precious weeks before Tessa's time finally runs out.
