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!

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.
