Head On by John Scalzi

Head On by John Scalzi, 335 pages

From the MARC: "Hilketa is a frenetic and violent pastime where players attack each other with swords and hammers. The main goal of the game: obtain your opponent's head and carry it through the goalposts. With flesh and bone bodies, a sport like this would be impossible. But all the players are "threeps," robot-like bodies controlled by people with Haden's Syndrome, so anything goes. No one gets hurt, but the brutality is real and the crowds love it.Until a star athlete drops dead on the playing field.Is it an accident or murder? FBI Agents and Haden-related crime investigators, Chris Shane and Leslie Vann, are called in to uncover the truth--and in doing so travel to the darker side of the fast-growing sport of Hilketa, where fortunes are made or lost, and where players and owners do whatever it takes to win, on and off the field."

Head On is a rare occurance of the sophomore effort of a series almost being equal to its first. I find myself coming back to this series as a comfort listen, as I really enjoy the audiobooks.
