Hi Kay,
Don't know if anyone has suggested it - I've got pretty slow internet here at the moment and didn't really fancy going through the page and pages of replies for this thread! - The Time Traveller's Wife by Audrey Niffenegger is a really good book. Everyone I know who's read it has loved it. I think they've just finished making a movie of it and it will be released this year, so you should try and read it before the movie comes out!
Also, The Bride Stripped Bare is a good book...bit naughty though - not one for the kids! It was originally released as by Anonymous, but then the author's identity got out and now they market it as by her, Nikki Gemmell. I think originally she wanted to write it anonymously so that she could try and write it with quite 'out there' honesty. I think if I'd written it, I wouldn't want anyone to know I had! Anyway, it's a good book, different, and think you can get it in the US through Amazon for super cheap second hand as it's a couple of years old now.
Hope that helps!
JB
