Mary Kubica has done it again! What a great read that was! I totally got it wrong and the twist was amazing! I will say this book made me sad, reading about the family dynamics! Reading the complexity of each person's personality and going through life! I highly recommend reading!

Mary Kubica is the queen of suburban suspense, and It’s Not Her is a masterclass in psychological tension. She has an incredible knack for making a quiet neighborhood feel completely ominous, weaving a story about identity and the terrifying secrets we keep from those closest to us.
​The pacing is lean and punchy, with POV shifts and timeline reveals that kept me second-guessing every theory. While the middle slowed down slightly to lay the groundwork, the payoff was massive—shocking, yet heartbreakingly logical. If you loved Local Woman Missing, this is a mandatory addition to your TBR pile. It’s twisty, emotional, and deeply unsettling.
