Harlen Coben has one called "Fool me once" that is supposed to be VERY good. Two friends came to me and said "OOOOHHHHH....good book!" So I'm getting it from the library. I also love Janet Evanovich. She has I think 4 with another author where the main character is Nick Fox (world renowned thief and on the FBI's most wanted list) and his cohort an FBI agent. I forget her name, sorry. They're easy reads and very cute.
