High Five is the fifth book in the saga of Stephanie Plum, who is still learning to be a bounty hunter. The plot line of this book follows Stephanie as she searches for Uncle Fred, and only incidentally involves bringing in bail jumpers. She seems slightly less naive in this book, and more on the ball in her chosen profession. She deepens her relationship with Ranger, while at the same time trying to figure out where she stands with Morelli.
