Amazing was always!
Format: Kindle
Frieda had been my favorite author since I started reading again last year. I've read every book and they've all been amazing, this one is no exception. I was hooked immediately! She's really good at grabbing you within the first chapter lol. So many plot twists and the ending was phenomena! I see she has another book releasing this year and I am so excited!

Another brilliant read!
Format: Kindle
I absolutely loved this book and read it in a day. The second POV towards the end of the book with Ronnie’s chapters was a refreshing change and enables the reader to understand little Teddy’s backstory. A tough beginning for sure. I loved the high stakes throughout the book, the twists and, as always, the surprising turn of events at the end. There were a few things I wasn’t sure about. Would Naomi have gone to the birthday party and done what she did with so much to risk? As a mother, I’m not sure it made sense and somehow it frustrated me a little. I won’t go into specifics but the hair cutting was sooo triggering! I thought Teddy’s secret code was a clever addition to the story and ramped up the pace at the end. Really scary and I thought they’d never make it. I think with a little more development and detail this book would have been a clear 5 star winner for me. It was almost over too soon. But I loved the premise. As a result, I gave it 4.4 stars. It was a quick and fun read, as all Freida’s books are. She definitely is an auto-buy author. I’m obsessed!

Another Great Read
Format: Paperback
Yet another "Whodunit" book. No matter how many times I pick up a Freida McFadden book, rest assured it will be great. The books are easy to read; not too prolonged yet the endings are incredible. This book does not disappoint. Highly recommend!!

Great read ⭐️⭐️⭐️⭐️⭐️
Format: Paperback
The Divorce by Frieda McFadden was everything I’ve come to expect from Frieda — addictive, suspenseful, fast-paced, and filled with shocking twists that completely caught me off guard. In true Frieda fashion, just when I thought I had the story figured out, she turned everything upside down. She has such a talent for making ordinary situations feel unsettling and keeping the reader questioning every character’s motives until the very end. What I loved most was how quickly this story pulled me in. The tension builds chapter by chapter, and the short, fast-moving chapters make it almost impossible to stop reading. Every reveal added another layer to the story, and I constantly changed my mind about who could be trusted. Frieda always knows how to create characters that are flawed, complicated, and just suspicious enough to keep you hooked. The emotional side of the story mixed perfectly with the thriller aspect. The themes of betrayal, secrets, marriage, and manipulation made the story feel intense and realistic while still delivering the dramatic twists her readers love. The ending was absolutely wild and left me sitting there replaying everything in my head afterward. Another fabulous read from Frieda McFadden. She truly has become one of my automatic-read authors because she never fails to entertain me. If you love psychological thrillers with nonstop tension, unreliable characters, and jaw-dropping endings, this one is definitely worth the read. ⭐⭐⭐⭐⭐

good book
Format: Kindle
A lot of fun and ridiculous twists and turns. But, unfortunately, this author still needs to hire a professional proofreader.
