Explosive Eighteen by Janet Evanovich

In Explosive Eighteen, Stephanie Plum continues her adventures (and mostly misadventures) as a bounty hunter in New Jersey. The story begins with Stephanie returning from Hawaii and finding a photo of an unknown man in her bag. She tosses out the photo then discovers that everyone and his brother is looking for it. As usual, Steph has car issues, romantic issues and incompetence issues.

There are some funny scenes but there's not enough Ranger or Morelli--or even Grandma Mazur for that matter. Entertaining, but not the best in the series.
