Aspiring writer Savannah’s scheme to meet superstar horror novelist Bennett Bryson turns out better than she ever imagined: not only does her charming and handsome literary idol offer to read her work, he is instantly smitten with her. After a whirlwind romance, Savannah says "yes" to marriage, and the two settle into Bennett's secluded upstate home. But just as Savannah thinks she has it made, cracks appear in her perfect new life. Bennett's behavior becomes dark and controlling: he criticizes Savannah’s writing, dictates her permitted activities, and spends most of his time locked in his office, forbidding her from entering. And everywhere, Savannah cannot escape the shadow of Bennett's first wife, the free-spirited and passionate artist Poppy, who died in a tragic accident, but who seems still to be Savannah’s rival for Bennett's affection. Then comes an enigmatic warning: Bennett is not who he seems. The women that came before Savannah have disappeared. And Savannah could be next. Isolated and unsure whom to trust, Savannah tries to piece together the mystery of the man she married, and the woman he married first. But Savannah has no idea what her husband is really hiding. And someone out there knows Savannah has secrets of her own. As these two writers will learn the hard way—past really is prologue.
