And suitable for a pre-teen girl.....
I am giving her a kindle fire for Christmas and have started selecting some books to get her started. She is frighteningly bright and I am sure will find all the apps she wants. Her parents may choose to block access to the amazon store, though I hope they will only stop her actually spending money

Having spent quite enough money on her by getting the kindle, I don't want to actually BUY books for her. I've downloaded the Amazon freebies that look to be of interest, and am looking elsewhere for sideloadable books. I can convert formats, of course. Preferably nothing too gender specific, there are already enough cultural pressures to girly conformity without me adding more.
Thoughts?
