A New York Times Editors Choice and one of the Washington Post s 5 Best Thrillers of the Year [A] knockout debut novel . . . As dark and twisted and alluring as the night-cloaked streets of nineteenth-century London, and this book is as much a fascinating psychological query as it is a gripping narrative. Benjamin Percy, author of Red Moon Summoned to life by strange potions, Hyde knows not when or how long he will have control of the body. When dormant, he watches Dr. Jekyll from a remove, conscious of this other, high-class life but without influence. As the experiment continues, their mutual existence is threatened, not only by the uncertainties of untested science, but also by a mysterious stalker. Hyde is being taunted possibly framed. Girls have gone missing; someone has been killed. Who stands watching in the shadows? In the blur of this shared consciousness, can Hyde ever be confident these crimes were not committed by his hand? A pleasure . . . Rich in gloomy, moody atmosphere (Levine s London has a brutal steampunk quality), and its narrator s plight is genuinely poignant. New York Times Book Review"
