I've been reading a lot lately and have lots to recommend:
Jennifer Weiner books, the latest is Fly Away Home, but they are all good.
Jennifer Crusie books - again they are all good. She writes really good romance books that are just a little more in depth than Harlequin romances, but still have good sizzle
The Host - the "adult" book by Stephanie Myers who wrote the Twilight series (meaning it was written for adults, not that it is X rated
). This is a really good book.
