Harry Potter books, Forever by Judy Blume, The Babysitter Club, The Boxcar Children, but pretty much anything dealing with fantasy, mystery and even life.
There was this one book I had to read in school though, dealing with a boy being sent out for I think almost killing (maybe did kill, can't remember) a fellow student and having sent somewhere cold and snowy (Alaska, I think) and he met this polar bear that I belioeve almost caused him to die, then started to protect him once he showed a softer side. Gosh knows I honestly don't remember the name of the book though. Wish I could, because I loved it so much I wanted to buy it, haha.
