Lily Harper's third mission into the depths of the Underground City finds her battling its demonic residents in the Toy Store, level four of the hellish afterlife. Although Lily's guardian angel, Bill, is by her side every step of the way, Bill isn't much of a consolation when it comes to fighting things that go bump in the night. Instead, Lily would much prefer to rely on the brawn and brains of the two thousand year old Celtic warrior, Tallis Black. But Tallis is busy battling his own demons ... the internal type. While in the Underground City, Lily finds herself on the wrong end of a demon's wrath. A surprising encounter with the Master of the Underground City, Alaire, not only ensures her survival but also leaves her in the unenviable position of being in Alaire's debt. It's no secret that Alaire harbors a strange and unsettling fascination with Lily but she's more concerned with solving Tallis's deep and dark mysteries hidden beneath his stoic exterior. While becoming better acquainted with the master of the Underground City and coming ever closer to unraveling the enigma that is Tallis Black, Lily can only hope she makes it through hell and back.
