I like to use Overdrive from the library too for ebooks, as well as OneClickDigital from the library as well for audiobooks. I have not had great success with the variety of kids books on these from my library ( much better adult variety.) One option is to download a classic non children's book such as Huck Finn or swiss Family Robinson. I think i will do this on our upcoming trip. Since we will all be in the same room and need to turn the lights out at basically the same time, i am planning to download a classic audio book. I do love the stories, but also, if we listen at night, they lull us to sleep in record time. My favorite thing to do is to have the audiobook and the same book either in paperback or ebook (text) so that i can switch back and forth, but I can't always find both.
