Kitty Norville is back and in more trouble than ever.  Her recent run-in with werewolves traumatized by the horrors of war has made her start wondering how long the US government might have been covertly using werewolves in combat. Have any famous names in our own history might have actually been supernatural?  She's got suspicions about William Tecumseh Sherman.  Then an interview with the right vampire puts her on the trail of Wyatt Earp, vampire hunter.

But her investigations lead her to a clue about enigmatic vampire Roman and the mysterious Long Game played by vampires through the millennia.  That, plus a call for help from a powerful vampire ally in San Francisco, suddenly puts Kitty and her friends on the supernatural chessboard, pieces in dangerously active play.  And Kitty Norville is never content to be a pawn. . . .

“Vaughn's top-notch paranormal series is as strong as ever.  Readers of Kim Harrison's ‘Hollows’ series and Jim Butcher's ‘Dresden Files’ will appreciate Kitty's sarcastic wit, ingenuity, and independence.”
