Let's see...
I'm very partial to Nelson DeMille. Not funny, but very engrossing reads. Just finished Night Fall, and that was definitely a book I didn't want to put down. The only book of his that I couldn't get into was By the Rivers of Babylon. Charm School, while dated, is still an excellent book.
Faye Kellerman is another author that I grab the latest Peter Decker/Rina Lazarus book as soon as I can. They're best read in order to get the history of Peter and Rina, but the stories are self contained. Police procedural/mysteries with family dynamic and rich in Jewish Orthodox family life.
Anything by Marian Keyes is great. Probably my favorite is Lucy Sullivan is Getting Married, but I haven't hit a dud by her yet.
Meg Cabot's books for adults are good, too. The premise was that she was going to do them for an e-zine, so they're written as emails to each other. Once you get used to that format, they're cute reads. Boy Meets Girl, The Boy Next Door and one other book.
If you want romance with a good plot, Katie McAllister has some great ones. I happened to pick up "A Hard Day's Knight" so that I'd have something to read while waiting to pick up a friend from the airport. It was funny, racy and I learned quite a bit about Ren Faires and jousting.
I have feeling there are several of us who will be printing these out. It's great to find a new author to enjoy, especially when they've got a large catalog! My dad and I were a great resource for each other and once he passed, it took a long time to find authors I liked besides the ones we'd share books back and forth.
