Four to Score by Janet Evanovitch

This is not a book to read in bed, especially if your husband is trying to sleep. Laugh out loud uproarously funny stuff. Maxine is accused of stealing her ex-boyfriend's car so she runs him over, jumps bail and makes him jump through various hoops. He wants his love letters back, but they're not really love letters. Maxine sends him clues to find them and he has to do nasty things like dig through a bag of dog poop to find the clue. Stephanie and her posse of misfits goes after Maxine and tries to help the guy retrieve his letters.
Stephanie can't figure out the clues so she enlists the aid of Sally Sweet, a very large, very hairy cross-dresser who at the moment is playing in a drag band and living with a gay man. Sally will tell you he's straight. He influences Stephanie's 73-year-old grandma to join his band and eventually Lula will be their lead singer. But that's another story.
Then there is the question of men - Joe Morelli the good, but hot cop or Ranger who doesn't always follow the rules to get his man and who is in my opinion, even hotter.
Mayhem rules; cars and apartments are blown up leaving Stephanie high and dry, but there is always the 53 powder blue Buick and a bed at Joe's or Ranger's place.
I couldn't put this one down. LOVED! it.
