Head On by John Scalzi
Head On could work as a stand alone, but I think it's best to read Lock In first, to get a full feeling for the world and the main characters Chris and Vann. In the near future, a portion of the population has been affected by Haden’s syndrome, leaving some “locked in,” awake and aware, but unable to move or respond without computer/mechanical help. Our mystery this time around centers on the death of a Hilketa player. The player, like almost all Hilketa players, is a Haden, piloting his specialty threep remotely. Since the crime involves a Haden, it's FBI territory and this case falls to Chris and Vann. It doesn't hurt that Chris was at the game when the player died - Chris's father is potential investor in the Washington franchise.
The world Scalzi has created is well-done - believable and possible, but t heart, this is a police procedural with a cool sci-fi backdrop. Chris and Vann make great partners...
