Deep in the heart of old London town, spirits are drawn to the tempting lure of a lie . . . As Jess Ballard is struggling to adjust to her new life in London without Finn Carey to watch over her, she has thrown herself into her role as a Tracker, using her gift to communicate with and help as many spirits as she can. But just as she begins to settle into a new city, the city reveals a mystery too intriguing-and dangerous-to ignore. Something sinister is drawing restless spirits to a tiny old museum, luring them with a promise of salvation it cannot deliver upon. Meanwhile, Durupinen are being brutally attacked, and their gifts are being twisted with a Casting too terrible to comprehend. Can Jess discover the connection between the two mysteries before she-or someone she loves-becomes the next victim?
