Agree with the last 2! (haven't read the others but they'll go on my list now!)
I'll also add the Dark Hunter series by Sherilynn Kenyon and the Stephanie Plum series by Janet Evanovich. The former paranormal but absorbing for trade fic and the latter pee in your pants funny--I did not want to put either of these down!
If you like suspense put this one on your calendar for Feb 2010: They Never Die Quietly by D.M. Annechino. It's not yet released (amazon encore edition so you might be able to find a copy somewhere since it was published at one time). I am not kidding this book gave me heart palpitations! Seriously. Serial killer novel--it's kind of gruesome but I literally could not put it down. Amazing book!
