“A suspenseful page-turner…jolts and entertains the reader.” —Mary Higgins Clark

Inside Boston Doctors Hospital, patients are dying. In the glare of the operating room, they survive the surgeon’s knife. But in the dark, hollow silence of the night, they die. Suddenly, inexplicable, horribly. A tough, bright doctor will risk his career—his very life—to unmask the terrifying mystery. A dedicated young nurse unknowingly holds the answer. Together they will discover that no one is from…The Sisterhood.

“Terriffic…a compelling suspense tale.” —Clive Cussler
