This is my second Evanovich book, the first being Hot Six. And true to form, it has the same wit and charm and zinging one-liners. There is a lot of stuff on NASCAR racing which required a good knowledge of the subject, and which I appreciated up to a point. There are a lot of parallels with Hot Six, that seem to be formulaic.
Amusing Dog - in this one it's a St. Bernard, Beans. (Bob the retriever was in Hot Six)
Horny Man trying to get into heroines panties - in this one it's Sam Hooker, who endeared me with his breezy, Devil May Care attitude.
Going round and round again - in this book, our heros are constantly returning to parking lots of various restaurants and such.
Heroine - Alex Baraby, the heroine in this one, seems exactly like Stephanie Plum, no difference I could tell, so that the both of them are just Evanovich herself.
Crazy supporting cast - in this one, two notables: Felicia and Rosa, the tough Cuban fruit store ladies.
Some of the humor was a bit puerile, like Three Stooges slapstick, notably with the dog. That whole scene about poop was idiotic and not necessary.
Still, overall Motor Mouth does entertain.
