I just read
Back to the Bedroom by Janet Evanovich, which is currently still on sale for $0.79. I haven't read any of the Stephanie Plum books, but I have to say that now that I've read this one, I'm very tempted to at least read the first few. It was light and fun, with a cute hero and an uptight but adorable heroine. I'd recommend it, especially at this price, if you want to check out her style.
