Head On

“Head on” is the 2nd book in Scalzi's Lock In series. The series features a world where about 1% of the population have Hadens syndrome, a disease which “locks people in” to their body, although their minds still work. People with Haydens have a oasis/mmorpg-style world to interest with others virtually, or can take control of a robot, called threeps, where they can interact in the real world.

This second book in the series builds on the world in a fun way. Similar to the first book, it plays more like a detective novel in a science fiction world. I mentioned it reminds me of Asimov's “Caves of Steel”, which is true for this one as well.

The story follows the investigation into a death during a football-like game played by threeps (the robots). I'd put Head on fully in the “fun” category of books. It was immensely entertaining, great at world building and overall just a great ride. As a bonus, the audiobook is read by Wil Wheaton!
