My first grader came home the other day asking me if we could get some Club Penguin books. I had never heard of the series so I came browsing here on Amazon (the local library did not have the books). I ordered three since they were relatively inexpensive, and my daughter devoured them all within a week!
I looked through each book. The language is good and perfect for independent, young readers who are able to read chapter books. My daughter enjoys picking out her own path through the story, and reminded me of my own excitement when I was reading similar books at her age. There's quite a few titles in the series, and I plan on getting the rest of them. A fun, adventurous read!
