When a suburban real-estate agent, Cordelia Dulain is attacked by a strange creature in the woods behind her house, she barely escapes with her life. If not for the grisly wound, and her dog, Rufus’s odd behavior, she’d have chalked it up to too much wine. Shortly after her attack, Cordie’s latest fresh start takes a startling turn for the worse.

Attacked, kidnapped, and held for “quarantine”, Cordie tries desperately to escape her captors, but the true danger is building from within.
