A near-future thriller from one of the most popular science fiction writers of our age, Head On features the fictional sport of Hilketa: players controlling robot bodies beat each other with swords and hammers, fighting to obtain their opponents' heads and carry them through goals. But it's all harmless property damage - until a player drops dead during a game. An accident? Or a murder? In this stand-alone sequel to Lock In, investigators Chris and Leslie discover that as brutal as Hilketa is on the field, the stakes are even higher off it.
