I have used Epic books in past in my class. It is a nice collection of books that work on the web and on iPads/iPhone and Android devices. It creates an online library of books based on the topic interests of the child. At the start the child chooses the topics of interest and their level and then the program arranges a bunch of books in their account. They have a cheap deal for the summer if you are interested in trying it out. Available until June 12. Use code: SUMMER17
