Both my boys are heavy Kindle users (this after living for a long time in a country where English language books were expensive and it was hard to find exactly what you wanted when you wanted it). It can also be great when the book desired has font that is tricky for a young reader, e.g. my first grader had wanted to read The Hobbit, our copy was old with tiny font that was spaced very closely, the Kindle made it so easy to read visually.

One quick idea for you DD:
http://www.amazon.com/Magic-Faraway..._1?s=books&ie=UTF8&qid=1394830780&sr=1-1

Mostly, we use Amazon to find book related to ones we love.

Happy Reading!
