The Homelanders 3: The Truth of the Matter by Andrew Klavan.

This book is the third in the series, and I gave it a rating of four out of five. Charlie West is still being pursued by the Homelanders, a terrorist group out to overthrow democracy, and the police, who want him for escaping from prison. Charlie was convicted of murdering his former friend, Alex. Charlie finds Waterman in the first chapter, but he doesn't know if Waterman is good or bad. Charlie is taken to a remote, underground compound where he is given a serum to help him remember the past year of his life. It turns out Waterman is a good guy, but the Homesteaders overtake the compound, kill Waterman, and capture Charlie. Charlie eventually remembers how he got into this whole mess but realizes that his problems are far from over. He's on a top-secret mission, and there are only two people alive who know he's innocent of murder. Waterman, who is now dead, and Charlie can't remember the identity of the second person.

As in the first two books, there's a great deal of action for readers to enjoy. Charlie frequently gets captured by the Homelanders and then proceeds to escape. There are also several chase scenes involving the police. It's interesting how the author balances the action and violence with Charlie's religious beliefs and moral standards. He draws a great deal of strength from his karate teacher's lessons and his faith in God. It's a curious contrast to the shooting, explosions, and fight scenes in the plot.
