We've just bought ds a tablet for his 9th birthday, it has kindle on it and we have bought a flew books for him on Amazon for our half term holidays but he reads a book in a couple of days and there is no way we could fund his reading habit by purchasing ebooks. He normally reads books from school and the local library and we buy they odd one we can't find elsewhere.
The local library supplies ebooks for teenagers but not children. Is there a commercial library you can borrow from for a monthly fee - what do other people do?
