Head On is the second novel set in the “locked in” universe that John Scalzi created in Lock In. A virus called Haden’s Syndrome has caused a small percentage of the population to be “locked” inside their bodies. They can think but they can’t move or communicate in normal ways. Those people are called Hadens. Technology, in the form of a neural network, has made it possible for them to inhabit robots called threeps. The government has funded threeps as a health care benefit for Hadens but the funding is going dry.

Head On is a science fiction mystery featuring FBI agent Chris Shane, who happens to be a Haden. Shane has as much personality as soggy tofu; his edgier partner Vann is a better character. Thanks to his wealthy parents who are considering an investment in a Hilketa team, Shane (inhabiting a threep) is in a luxury box when a Hilketa player named Duane Chapman dies.

Hilketa is played on the field by threeps that are controlled by players who are off the field. The object of the game is to cut off the head of a designated opposing player and to score a goal by carrying, throwing, or punting the head over the goalposts. Threeps are usually operated by Hadens because their neural networks give them a reaction time advantage.

The players controlling the threeps aren’t supposed to be injured by their threep’s decapitation, but Chapman dies after his threep’s head is ripped off for the third time in the game. Shane is therefore front and center in a death investigation which arguably falls within the FBI’s jurisdiction because of the interstate nature of Hilketa, whose players are generally in a different state than the venue in which the game is played.

Hadens shouldn’t die from contact with their threeps, so establishing the cause of death is the first problem. Did Chapman’s use of a nutritional supplement that he didn’t endorse have anything to do with his death? Is the league covering something up?

As a science fiction murder mystery, Head On is about average. I enjoyed the science fiction setting more than the actual mystery, which has Shane watching a number of deaths pile up as he tries to piece together clues about how and why Chapman died and how the other deaths are related. The plot is reasonably complex but not wholly engaging, in part because Shane is just a dull guy. Still, Scalzi incorporates enough amusing background details (including vague suggestions about Hadens use threeps to have sex with other Hadens) to make the overall story more interesting than the mystery at its center.
