I Am The Messenger

I Am The Messenger by Markus Zusak

This book is written by the author of "The Book Thief", a book I absolutely adored. So now we are 2 for 2. I am really starting to love this guy. I think his books are smart, unique, and beautifully written. I loved this book - it was a page turner that I found myself immediately mesmerized  by it.(which has been rare lately - I find myself having such a hard time getting into most books I pick up...)
I don't want to say too much - but I would love for anyone who has read it to make a comment on what you thought of the ending...
Here is the overview The School Library Journal:
Nineteen-year-old cabbie Ed Kennedy has little in life to be proud of: his dad died of alcoholism, and he and his mom have few prospects for success. He has little to do except share a run-down apartment with his faithful yet smelly dog, drive his taxi, and play cards and drink with his amiable yet similarly washed-up friends. Then, after he stops a bank robbery, Ed begins receiving anonymous messages marked in code on playing cards in the mail, and almost immediately his life begins to swerve off its beaten-down path. Usually the messages instruct him to be at a certain address at a certain time. So with nothing to lose, Ed embarks on a series of missions as random as a toss of dice: sometimes daredevil, sometimes heartwarmingly safe. He rescues a woman from nightly rape by her husband. He brings a congregation to an abandoned parish. The ease with which he achieves results vacillates between facile and dangerous, and Ed's search for meaning drives him to complete every task. But the true driving force behind the novel itself is readers' knowledge that behind every turn looms the unknown presence - either good or evil - of the person or persons sending the messages. Zusak's characters, styling, and conversations are believably unpretentious, well conceived, and appropriately raw. Together, these key elements fuse into an enigmatically dark, almost film-noir atmosphere where unknowingly lost Ed Kennedy stumbles onto a mystery - or series of mysteries - that could very well make or break his life.
