Now You See Her
I think this was one of Patterson's best books. A young college girl is having a great time on Spring Break in Key West. She discovers her boyfriend cheating on her with her best friend. She's quite drunk but she has the keys to the boyfriend's "hot" car so she takes it for a ride. She's going like a bat out of hell , slams on the breaks and swerves to miss a dog on the roa and instead creams a guy on a bike. Of course the local cop is nearby, sees her sitting there in the car, the body of the guy she hit. . .and, well, her life changes forever.
