Mia's first reaction is outright disbelief. Obviously, a mistake has been made. Sixteen-year-old girls don't die. But, when the diagnosis is confirmed, she dives headlong into anger. If she has to die, why should it be of cancer? In fact, anything would be preferable to cancer. Better for her to say when, where, and especially how.

Determined to meet death on her own terms, Mia devises scheme after scheme to get the job done. A "fall" down the basement stairs, driving her car off a bridge, and even a dance with a train all end in her survival.

And through it all, Mia keeps her family and friends at arms' length with her destructive and hurtful behavior. With each failed suicide attempt and burned relationship, she slowly realizes that it's not the dying that she's afraid of, but the life she'll be leaving behind. Now, that life is in a shambles. As time begins to slip through her fingers and death is upon her, Mia fights to rebuild the bridges she has destroyed, but can she do it before the clock runs out?
