"Death Masks - Book 5 of the Dresden Files" by Jim Butcher (published 2003)

So, you're upset that the series about the Wizard named Harry is over. Well actually it isn't. Okay so this Harry's last name is Dresden, he lives in Chicago and he advertises that he is a "Wizard for Hire," but hey, he is a wizard. Oh yeah, he also has attitude. In his series "The Dresden Files," Jim Butcher has created not only a great character in Harry Dresden, but he has also reinvented the mythic and magical. In earlier books we learned their are different types of werewolves and the faery world is not so friendly.

In this book 5 of the series we join Harry, once again, in the middle of life:

Harry Dresden, Chicago's only practicing professional wizard, should be happy that business is pretty good for a change. But now he's getting more than he bargained for.
A duel with the Red Court of Vampires' champion, who must kill Harry to end the war between vampires and wizards...
Professional hit men using Harry for target practice.
Harry gets hired to find the missing Shroud of Turin.
A handless and headless corpse the Chicago police need identified and it seems only Harry could do it.
Not to mention the return of Harry's ex-girlfriend Susan, who's still struggling with her semivampiric nature. And who seems to have a new man in her life.
Some days, it just doesn't pay to get out of bed. No matter how much you're charging.

So it's Harry's life but with all that action it ain't boring.

The book starts off with Harry appearing on a "Jerry Springer" type TV show (hey it's Chicago), he only agrees to the appearance because another magical person needs to pass a message to Harry, but cannot afford to risk being seen with Harry. After all Harry did start the war between the Red Court Vampires and White Council Wizards. On the show are not only 2 representatives of the magical realm but 2 people to ridicule magic. One is a Catholic Priest and the other...well it turns out to be a major player from the Vampire's Red Court.

These other two "guests" also have something for Harry. After Harry's magical aura destroys the studio equipment, a hazard with Harry being a wizard; electronics quit around him, the vampire challenges Harry a duel to the death. This duel will end the war and all threats of violence against Harry's friends and family. The priest is there to hire Harry to find the recently stolen Shroud of Turin. After telling the vampire he'll think about it, Harry and the priest leave the studio only to be confronted by Chicago's head of the crime syndicate, Gentleman Johnny Marcone's hit-men.

The men shoot at Harry and he and the priest barely escape with their lives in Harry's beaten down VW Beetle. And this is only the first chapter. The action continues and never stops throughout this fifth edition of "The Dresden Files." Harry later teams up with the Knights of the Cross to fight the ultimate demons "Denarians," fallen angels that can manifest on earth.

What leads to an ultimate battle and some great fun. All throughout this book we are constantly treated to Harry's great wit and sarcasm. Do yourself a favor and start reading this series now.
