My name is Amelia Gray. I'm the Graveyard Queen. Restoring lost and abandoned cemeteries is my profession, but I'm starting to believe that my true calling is deciphering the riddles of the dead. Legend has it that Kroll Cemetery is a puzzle no one has ever been able to solve. For over half a century, the answer has remained hidden within the strange headstone inscriptions and intricate engravings. Because uncovering the mystery of that tiny, remote graveyard may come at a terrible price. Years after their mass death, Ezra Kroll's disciples lie unquiet, their tormented souls trapped within the walls of Kroll Cemetery, waiting to be released by someone strong and clever enough to solve the puzzle. For whatever reason, I'm being summoned to that graveyard by both the living and the dead. Every lead I follow, every clue I unravel brings me closer to an unlikely killer and to a destiny that will threaten my sanity and a future with my love, John Devlin.
