A darkness runs deep beneath London . . . Reeling from recent revelations and forced to lie for Kempthorne, the unthinkable happens: Dom fails the latent competency test. One more strike and he'll be deemed unstable, have his registration stripped, and the life he's come to love at Kempthorne & Co will be over. If that weren't bad enough, someone is stalking him, taunting him. Someone who knows what Dom did all those years ago. While Dom juggles Kempthorne's lies and his own shady past, latents are being murdered. The police won't help, so it's up to Dom, Kempthorne & new-recruit Kage (Hollywood) to find the killer, before they strike too close to home. Dom soon finds himself at the heart of it all with his control slipping, his trick breaking free, and the shadows rising. He's coming undone. And for unstable latents, there's only one way out . . . Contains mature themes.
