Classic Kids Book
Format: Board book
The Rainbow Fish is one of those children’s books that has been around forever for a reason. The story is sweet and the illustrations are beautiful. It is a great book to read with kids and one that seems to stick around in family libraries for years.

Great illustrations but not sure about the story
Format: Board book
My toddler is obsessed with all things fish, so when she picked out The Rainbow Fish from Amazon search. The illustrations are gorgeous, and my daughter is mesmerized by the sparkly, foil-like scales on the fish. She keeps pointing at them every time we read it, and it’s become a bedtime favorite just for the shiny colors! One thing I found a little odd is the story: the Rainbow Fish gives away all her beautiful scales to make friends. It’s a sweet message about sharing, but as a parent I admit it made me scratch my head a bit (I wasn’t sure if my toddler really gets why the fish parts with all her sparkles). Still, it’s a friendly tale and we enjoy reading it together.

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

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. ⭐⭐⭐⭐⭐
