Notorious Nineteen by Janet Evanovich

Okay- so we have the usual "bones" of the book, i.e. Morelli, Ranger, Lula and Grandma.  Ranger is in a pickle and Stephanie is along for the ride.  Some harrowing circumstances push this almost into "thriller" territory but not quite.  There's still enough humor to make this a light mystery.  If you're well read in this genre, you'll figure out the plot before it's revealed.  Not to worry though, it's an enjoyable read.
