Critically celebrated novelist Scott Spencer delivers aRosemary's Baby-like novel of gothic horror, set against the backdrop of modern-day Upper East Side Manhattan.

Alex and Leslie Twisden lead charmed lives--fabulous careers, a luxurious home in Manhattan, a passionate marriage. What's missing is a child, and as they try one infertility treatment after another desire becomes obsession. As a last-ditch attempt to make their dream of parenthood a reality, the Twisdens travel to Slovenia, where they undergo a painful procedure that gives them what they've so fervently wanted...but with awful consequences.

Ten years later, coddled and living in a house of secrets, the twins Adam and Alice find themselves locked into their rooms every night, with sounds coming from their parents' bedroom growing and more disturbing.

Desperate for answers, the twins set out on a quest to uncover the truth about the man and woman who raised them. What they discover will reveal a threat so terrible that it must be escaped, at any cost.
