I Am the Messenger By Markus Zusak

Description

protect the diamonds
survive the clubs
dig deep through the spades
feel the hearts

Ed Kennedy is an underage cabdriver without much of a future. He's pathetic at playing cards, hopelessly in love with his best friend, Audrey, and utterly devoted to his coffee-drinking dog, the Doorman. His life is one of peaceful routine and incompetence until he inadvertently stops a bank robbery.

That's when the first ace arrives in the mail.

That's when Ed becomes the messenger.

Chosen to care, he makes his way through town helping and hurting (when necessary) until only one question remains: Who's behind Ed's mission?
