Sizzling Sixteen, by Janet Evanovich

Here I am again, complaining about a mystery series gone bad. The Stephanie Plum novels used to be fun--full of quirky characters in Stephanie's family, at her job as a bounty hunter, and generally scattered around Trenton, New jersey, where she lives. Now, the characters have become tedious and predictable, highlighting the ridiculous plots. Even the "sexual tension" between Stephanie and her two men--Ranger and Morelli--has lost its zip. Sizzling Sixteen isn't worth another sentence.
