I recently read a great book called I Capture The Castle. It was written by Dodie Smith (the woman who wrote 101 Dalmations) in 1948. It was out of print for years, but I'm so glad it's in print again so that I could discover it!
It's the journal of 17-year-old Cassandra and her life with her family in a crumbling English castle. The voice of Cassandra is just so hilarious. Her life is slowly falling apart, and she tries to pick up the pieces for her family, whilst keeping herself sane by writing in her journal.
My favorite line is "I know all about the facts of life. And I don't think much of them."
Apparently the book was made into a movie in 2003, so I can't wait to find it and watch it!
