Thirty-year-old caregiver Callie Rennick has spent her whole life cleaning up after people—parents, employers, lovers, strangers. In the houses where the forgotten elderly sleep, she is the only one who still hears their breathing. The only one who listens. And the only one brave enough to end their suffering. At least, that’s what she tells herself. That it’s mercy. That it’s kindness. That it’s love. When Callie quietly swaps the medication of wealthy retiree Henrik Dorsey, she expects a new life to finally begin. Instead, she’s thrown back into poverty, loneliness, and the job she knows too well: caring for those who can no longer care for themselves. Her next patient—Agnes Holloway, bedridden and voiceless—becomes both a burden and a mirror. Every day, Callie sees the future she fears most: aging alone, unwanted, discarded like furniture. And every day, the line between compassion and cruelty blurs a little more. A young man named Tavian Blake enters her life with warmth she has never known. Affection turns to obsession. Obsession turns to violence. And when Tavian betrays her, something inside Callie finally snaps. From that moment on, the houses grow quieter. The deaths grow cleaner. The pillow grows familiar in her hands. But Callie’s final client, Eloise Trammell, is not as helpless as she seems. Hidden cameras watch the rooms Callie thought belonged to her alone, and a grieving daughter begins stitching together the truth behind the “silent passings.” As the world closes in, Callie must face the horror she’s created— the bodies, the lies, the tenderness she mistook for love, and the terrifying possibility that the only monster in these homes was her.
