Nat, I'll have to have a look for Harlan Coben as I've never heard of him.

Naomi, if you've been given some of Janet Evanovich's stuff of the Stephanie Plum series, it's worth starting at the beginning with "One for the Money" and working your way through the series. I'm just re-reading Twelve Sharp, which is her current one in the series. You can read them as 'stand alone' books, but it's fun to read them in order. (each book has a number in the title, eg One for the Money, Two for the Dough etc, so you can work out the order really easy). It's fun to follow the progress of Stephanie's life!

Another one that I love is Linda Fairstein - she writes crime stuff about her character Alex Cooper who is a District Attorney for sex crimes. It's not as heavy as it sounds. It's written similarly to Kathy Reichs stuff. Again, a good read.
