Dorothy the Rainbow Fairy by Integrated is a great science storybook.
Like most good digital storybooks, you can read the story yourself or let the book read it for you. It also has the typical interactive touch elements on all pages.
But it also has items I have not seen in other story books. Some of those interactive elements are modeled after pop-up or slider books. In most pages you can slide a virtual tab, or spin a virtual wheel.
The book is about fairies and rainbows. And if the book is correct, I might have learned a few things I didn’t know about the origins of rainbows. Overall a high quality and beautiful digital book.
