This was just alright. There were definitely some surprising moments and twists I didn’t see coming, but overall it felt like other thrillers I’ve read. Nothing overly stood out as impressive to me, but it was well written - I would read more from Mary Kubica in the future. Looking back I wasn’t a big fan of any of the characters and I wasn’t really rooting for anyone. I did feel the pressure that Courtney felt to find Reese and I felt her confusion throughout the investigation, but I didn’t like her so to speak. I found myself highly skeptical of everyone and actually creating scarier outcomes in my mind than what actually happened. The thing with thrillers, for me, is I am supposed to feel shocked and when they are formulaic or similar to other thrillers I’ve read, it’s hard for me to say that it was really well done. Absolutely not a bad Reid. It was easy if you’re into thrillers I would recommend, but it definitely is not one of my top favorites.

I really enjoyed listening to It’s Not Her! The narration did a great job capturing each POV, balancing the characters’ emotions with the atmosphere of the story. I thought the transitions between the past and present were smooth and kept me invested. I enjoyed the buildup to discovering what happened to Reese more than the ending itself, but I appreciated the creative misdirection, especially Courtney’s suspicions about her husband and Wyatt.

The twists in this one just kept coming! I thought I had it all figured out several times, and I was still wrong at the end. I don't think I've ever read a Mary Kubica book with this many twists and turns, and I loved it! There were some unrealistic parts, but we'll just overlook those.

Courtney Gray’s family vacation at a quiet lakeside resort turns horrifying when she discovers her brother and sister-in-law murdered in their cottage, while her teenage niece Reese has vanished without a trace. What begins as a brutal family tragedy quickly expands into something darker, with buried tensions, fractured relationships, and unsettling secrets rising to the surface. Suspense builds around not just who is responsible, but what really happened to Reese and how far people will go to hide the truth. Wow wow wow. I feel so bamboozled in the best possible way. I thought I knew what happened and where this book was going and then I didn’t. Rinse and repeat that for the entire book. You literally DO NOT know the truth at all, no matter how much you think you do. My favorite part was the alternating timelines of what happens after the incident and what happens in the days leading up to it. Both perspectives come together to give you a fully baked pie of suspense, slowly revealing how everything connects. I love Mary Kubica, so much. This book is wild. Read it if you can.

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!
