For a famous writer who can no longer write, every day is a torment. Julian Croft's life, managed by his elegant wife Eleanor, is a silent prison of his own making. To save his career, Eleanor makes a dangerous gambit: she hires Ava, a personal assistant whose résumé is as flawless as her looks. Ava is a miracle, a whisper of understanding in the sterile quiet, and she quickly becomes indispensable to the fragile author. But miracles have a price. As Ava's devotion becomes obsession and her methods grow more intimate, the silent house becomes a battleground of secrets, desire, and psychological warfare. Because in the world of Julian Croft, the most terrifying stories aren't the ones he writes, but the one he has just started living.
