Good Books??

Tbh, i am a bookworm. I love reading, but i have ran out of books to read. I am 14, and a girl, and i am quite an advanced reader, as i have just read Little Women. Can anyone recommend any good books for me to get out of the library? And also, i would like to read an autobiography, but i don't know whose to read :S HELP! Please :). Thanks in advance x.
