A powerful story of hope and friendship, from the author of The Bone Sparrow.

A boy awakens in the Afterlife, with a pocketful of vague memories, a key, a raven, and a mysterious Atlas to guide him as he sets out to piece together the mystery of his final moments...

Back on Earth, Twiggy is a street kid with a missing dad. But when he meets Flea, a cheerful pickpocket, the pair become fast friends, better even than blood family itself. Together, Twig and Flea raise themselves on the crime-ridden streets, taking what they need and giving the rest to the even-poorer. Life is good, as long as they have each other. But the all-powerful Boss who rules the streets has other plans.

Loyalty will be tested, and a cruel twist of fate will lead to an act of ultimate betrayal that will tear the friends apart ... forever?
