Turn Coat (The Dresden Files #11)

When it comes to the magical ruling body known as the White Council, Harry keeps his nose clean and his head down. For years, the Council has held a death mark over Harry's head. He's still thought of as a black sheep by some and as a sacrificial lamb by others. But none regard him with more suspicion and disdain than Morgan, a veteran Warden with a grudge against anyone who bends the rules.
