I'm heading on a couple of vacations in the next month and I need some suggestions on books to download for my trips! I want stuff that's not too involved or heavy but I like things with a bit of substance (one of my favorite books like that is Water for Elephants for example). I'm open to any suggestions as long as I can get it cheap on the nook or kindle app. Genre doesn't really matter, though lately I've been reading mostly YA books and Game of Thrones series with a Stephen King thrown in.
What books would you suggest I download for my trips?
