Favorite childhood book
Format: Board book, Format: Board book
The Rainbow Fish was my absolute favorite book when I was little, so I had to get it for my kids too. The sparkly scales are still just as magical as I remembered and honestly make the whole book feel special.
The story is sweet, the illustrations are beautiful, and it’s one of those classic children’s books that actually sticks with you growing up. Reading it now feels really nostalgic for me, and my kids love looking at all the shiny pages. Such a cute book to have in your collection.

Adorable, sparkly little board book for youngsters!
Format: Board book
Quick book about sharing and friendship. Beautiful board book with sparkles on the fish. Including the cover, there are 6 pages to turn. I bought for the kids I babysit (age 11 months and age 4). Excellent little book for a child or teacher's library!
