Their sanctuary. Their bond. His final assault. Sera Locke fought her way through nightmares, dark magic, and the very boundaries of death to bring Nathaniel home. Now he is the house—the hearth, the walls, the stone beneath her feet—and Hollowmere has never known such peace. It lasts three weeks. When a creeping blight devours a rose in the garden, consuming Sera's life magic and leaving nothing but cold ash, she recognizes the signature immediately. Julian Mortmain—colder and more refined than his father—hasn't come to destroy Hollowmere. He's come to hollow it out from within. To rot the Hearthstone. To unwrite the Locke legacy from the very soil. Sera is exhausted. She has given everything. And Julian has built a weapon that feeds on exactly what she is. But she is not the woman she was. And Nathaniel is no longer a ghost she must protect. He is her fortress. And together, they are ready to declare war. The Hollow Hearth is the breathtaking conclusion to The Witches of Hollowmere—a gothic romantic fantasy where love built a home, and love will be what saves it.
