Can strangers become sisters, a long-lost father become a dad, and can love really conquer all? The challenge is extreme—the stakes have never been higher.

The fortune cookies tease her. You will lead a long and happy life. Those dumb things are never right.

Chessie Madrid wants to fall in love, she wants to fly airplanes, and most of all she wants to live longer than 6752 days. With a fatal disease camped inside of her wreaking havoc since she turned sixteen, the doctor's predictions are far more sinister. Preparing for death is a total drag.

Instead, Chessie makes a list of her deepest desires, keeping her impending demise a secret, and being pretend-well. When the list suddenly starts to come true, sending Chessie's life and everything in it reeling, it's a case of being careless what you wish for.

With a new sister she's always dreamed of, a father who's a nightmare, and a lesson in love arriving all at once, Chessie makes her last wish the one that will matter most of all—to live or die trying.
