**She's family now. But can I trust her?**

When my stepsister **Alison** moves in to look after my mother, everyone in my family is grateful. Alison's a nurse, and she says she just wants to help. **But I don't trust her.**

Years ago, when Alison and I were the same age as my own son **Isaac**, I made a terrible mistake that tore Alison's world apart. Now the look in her icy blue eyes tells me: **she knows exactly what I did.**

I'm certain she's responsible for my mother getting weaker. I don't like the way she's pushing me out, isolating me... and getting way too close to my husband, **Nick**.

I'm watching her. And **I'll do anything to keep my family safe. But I have no idea just how much danger we're in...**

**A totally unputdownable, twisty story of family secrets that have deadly consequences. Perfect for fans of Shari Lapena, Freida McFadden, and Daniel Hurst.**
