Mark and his wife Erin are in the middle of an argument when the lights go out. It's just a blackout. A summer grid failure. The kind of thing that happens when the heat index holds above ninety-five for too many days. Nothing to worry about. Then he finds the blood. A physician trained to read trauma scenes, Mark follows the evidence through his dark house with the cold precision of a man who has learned to stay behind the glass. He knows what the blood volume means. He knows what the spray pattern means. He knows, before he is ready to know it, exactly what has happened in his basement tonight. What he doesn't know — what he can't know — is what is happening on the other side of his neighbor's fence. The Husband is the first book in The Blackout series — a relentless, multi-POV psychological thriller in which the same catastrophic night unfolds through four different sets of eyes. Told entirely from Mark's perspective, this is the story of a man whose medical training gives him every answer except the one he needs most. For readers who love The Silent Patient , I Am Pilgrim , and The Chain — a propulsive, suffocating thriller that doesn't let you breathe until the final line. Book One of four. Continue the night in The Witness, available now.
