Three patients. One is hunting her. She cannot trust her own notes.

For thirty years, Dr. Mari Vega has been the person Santa Fe sends its most damaged people to, and she has never once been wrong about who is dangerous. Then, in a single week, three new patients arrive without referrals. A widow who does not believe her husband fell from the bell tower of La Fonda. A composed British lawyer who says he wants to stop himself before he hurts someone. A young woman who keeps asking whether the people who do harm and the people they harm are the same.

Her case notes have always been the only weapon she needed. They are also the only record of the malpractice case that gutted her practice seven years ago. As her estranged daughter comes home carrying a folder she will not open, and her oldest friend warns her that a man here has changed his face, Mari notices something that should not be possible: the notes she swears she wrote are not the notes in her file.

Someone is writing her. To find out who, she will have to trust the one instrument she has stopped believing, herself.

Told in two voices, the clinical file and the private journal, where only one of them can be trusted, The Mother I Did Not Know is a slow-burn Latina psychological suspense and the first book in The Casita Series.

For listeners of The Silent Patient, Mexican Gothic, The Push, and The Hacienda.
