Just finished Coben's "Promise Me". As usual, he delivers.
Ben -- if this is one of the authors you haven't tried yet, give it a go. I don't think you'll be disappointed.
BTW - Dunning just had another one hit in paperback. The Bookwoman's Last Fling. It's on deck. Right now I'm going to start Ian Rankin's "A Question of Blood."
When I run out of things by my favorites and start looking around for someone new I tend to look at the list of books that have won the Edgar Award and try those writers. That's how I came by checking out Rankin.
