The authors were kind enough to send me a few of these. I gave them to my kid on Christmas and he loved them. Sorry, loves. Ever since he got these, things are reframed around these books. He'll play weatherman using maps in the house, and refer to the books. He also has read them to the 3 month old. ^_^
You can see below that it's a picture book, that gives you some interesting information about a related topic that starts with each letter. They are pretty neat. And each book uses OpenDyslexic 2 and 3.
