The doctor's diagnosis for April Lancaster is not good. April has a brain tumor which cannot be operated on. She's only 18, and her future is uncertain. But when she meets Mark Gianni, a 21-year-old with a passion for car racing, things change.

Mark is handsome and charming--and has cystic fibrosis. Despite herself, April falls completely in love with him. April says yes when Mark asks her to marry him. But a racing accident aggravates Mark's CF, and April must make a decision that will change the course of her life forever.
