Some houses become haunted. One house became hungry.
Restoration architect Clara Ellison inherits a storm-battered estate on the Maine coast from a relative she never knew existed. She comes to sell it. She stays because the house is impossible: hallways that lengthen at night, portraits whose faces slowly disappear, thousands of names carved beneath the wallpaper. One of them is hers.
She isn't alone. Lucien has lived inside Sablecliff for four hundred years and hasn't aged a day. He says he isn't trapped. He says he's the only thing standing between the world and a forgetting that has already begun to spread, and every time he dies to hold it back, the house rebuilds him and takes another piece of who he is.
The house wants Clara. It always wanted an Ellison. And the closer she and Lucien fall, the more certain he becomes of the one unbearable rule: love her, and the house may take her from his memory forever.
She's an architect. She solves impossible buildings for a living. But this one wants to be paid in the people they love, and the price is coming due.
Save the house, and lose him. Save him, and lose the world. Unless she can rewrite what the house was built to do.
