The perdition score
(Book)

"The request from Thomas Abbot, the Augur of the Sub Rosa council, couldn't come at a better time for James Stark, aka Sandman Slim. For a man who's most recently met Death and Death's killer, a few months of normal life is more than he can handle. He needs a little action, and now Abbott wants Stark and Candy to investigate the disappearance of a young boy and help uncover council members who might be tied to Wormwood's power brokers. Stark's plans change when he meets a dying angel who gives him a vial of a mysterious black liquid that could be a secret weapon in the ongoing war between angels who want to allow human souls into Heaven and rebel angels willing to die to keep them out"--,Provided by publisher.
