Mitch Sayer and Piper Wynne meet on a plane and he later finds a crumpled letter on the plane's floor which affects him to the degree that he feels he must find out who wrote it. He later discovers that he and Piper share the same city and work near each other, so this leads to a few dates for them both. Piper is running from her past and a mistake she can't forgive herself for, and Mitch's growing attraction to her causes her to feel threatened.
I liked Mitch as a character, but Piper behaved, for the most part, like an idiot. There's feeling guilty for what you did, and then there's 'I don't deserve to live' level drama. Piper's behavior is grossly unrealistic and downright silly at times. There are some decent supporting characters, including a married couple who befriend Piper. However, Piper's family includes kids named "Thai" and "Asia" (really?). It's not a truly bad book, but it's a mediocre romance at best.
Piper is running from her family in guilt. The guy she met on the airplane is going to solve the mystery.
