Beware when a vampire loses control!

In 1850s London, most mortals are not aware that vampires walk amongst them. Lord Sebastian Hawthorne, himself a vampire, intends to keep it that way. Unfortunately, when someone begins killing off well-known citizens—in gruesome ways—all signs point to a newborn vampire unable to control the bloodlust.

Marcus Dwyer, a fellow vampire, admits to turning a woman for companionship, and now she's out of control. He needs Sebastian's help. Together, Marcus, Sebastian and Theo, Sebastian's human friend, set out to catch the rogue killer before she exposes their secret.

Will they find her in time? Or will the police capture her first, and will their discovery lay waste to the vampires' immortal world?
