No Child of Mine Lewis, Susan

Alex Lake thought she knew her teenage stepdaughter. Then the unthinkable happens — a toddler in Ottilie's care ends up in hospital with injuries that look disturbingly deliberate. The police are circling, social services are asking questions, and Alex is caught between protecting her family and confronting a truth she's terrified to face. Susan Lewis pulls no punches in this domestic thriller that asks how well we ever really know the people we live with. It's tense, claustrophobic, and uncomfortably plausible — the kind of story that makes you second-guess every family dynamic you thought you understood. For readers who like their suspense rooted in real-world dread rather than serial killers.
