Ooo, that Jennifer Weiner sounds intriguing, I'll have to renew my library card.
My favourite author is Anne McCaffrey. I love all her Pern books. I could read them over and over again (and have!).
I also love the Harry Potter books.
On a slightly off topic note, if anyone loves medieval history, and comedy, they would most likely love this web comic I read everyday.
Get Medieval
Make sure you start at the beginning if you're going to read it. It's awesome!
