Books4Kid needs an interface design for an application for iPad, which is focused on children

This is what a business in Russian Federation was looking for in their app design

I need to create an interface design for an application for iPad, which is focused on children. The app is a bookshelf for interactive kids books. Also I need to create an icon for the app.

I am looking for new ideas for interface.
Interface should be oriented to small children (for 3 -7 years old).

I attached requirements list and examples of understanding the application interface.

For example see attached links:
