I love The Chronicles of Narnia all 7 of them. Re-reading them as an adult is really cool because even though they were written during World War II, they relate to a lot of the problems that are occur today. My favorite one is the last book, The Last Battle. I love C.S Lewis as a writer, I know some of his works are difficult to read and understand but I love how he puts Christianity into his writing.
Another series that I love is of course the Harry Potter books. (But think all of you know that I love those books)
I posted about her before, but I feel that every girl should read all the books written by Jan Austen.
