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.

The Good Democracy is at Risk
Format: Kindle
This is as close to a page-turner as a prosecutor's brief can get. No words are wasted as the author describes how Donald Trump and his minions have used their raw power to lay waste to the "good" that is the beating heart of American democracy, putting democracy itself at risk. Only the people can fix it.

Sweet, Simple, and Full of Love🙌🏽❤️
Format: Hardcover, Format: Hardcover
I Love Dad” is such a precious little book, especially if you’re a fan of The Very Hungry Caterpillar. It keeps that same classic Eric Carle charm—bright, colorful illustrations and a sweet, simple message that really tugs at your heart.
It’s the perfect way for little ones to express love for Dad in a fun and meaningful way. My daughter loved pointing out the animals and colors, and it’s become one of our go-to bedtime reads. 🥹
The wording is short and sweet, it’s easy for toddlers to understand, and perfect for new readers to follow along. It also makes such a thoughtful gift for Father’s Day, a baby shower, or just because.
If you’re looking for a feel-good story that celebrates dads with love and playfulness, this book is a total gem. 💙📖
