Cross your heart.
Hope not to die.

Diagnosed with a rare and untreatable heart condition, Scarlet has come to terms with the fact that she's going to die. Literally of a broken heart. It could be tomorrow, or it could be next year. But the clock is ticking...

All Scarlet asks is for a chance to attend high school—even if just for a week—a chance to be just like everyone else. But Scarlet can feel her heart beating out of control with each slammed locker and vicious taunt. Is this normal? Really? Yet there's more going on than she knows. And finding out the truth might just kill Scarlet before her heart does...
