Red Rose. The Uncollected Anthology, #14

Shadow finds himself on a Houston street with no memory of arriving there. In fact, remembers nothing about anything at all. In his pocket, he finds a single clue to his identity: an address that leads him to an alley behind a notorious tattoo shop owned by a local god. When he begins to see things that no one else can-magical things-Shadow suspects that he's not a normal amnesiac. Or even human. Can he unravel the mystery in time to save his life and the life of his only friend?
