Mia is the quintessential high school A-lister: popular, non-exclusively dating the captain of the soccer team, extremely high GPA, everything Mia's mother has ever wanted. When you have everything good going your way, you have everything to lose. After Mia finds out she has leukemia, she feels like everything she has achieved will slip away from her. So she decides to keep her illness a secret from all her friends and her boyfriend. The only one she lets in is her lifelong best friend, Gyver-the guy next door who is poised to become so much more in her life. Mia is always looking for signs in her everyday life, to shape her decisions, and now that she's sick, she's desperate for a sign that she is going to survive.
