I'm was a dedicated Stephanie Plum, Morelli, and Ranger fan before I read this latest Evanovich novel. I didn't think the plots could get better, but this one left me wishing I could have the next installment before next year. This one left me laughing and crying, and I think it was the best yet!A Georgia fan
