Head On by John Scalzi

Writing: 5 Characters: 3.5 Plot: 4.5

Classic Scalzi — a cool, well-explored, futuristic world with non-stop and non-predictable action and funny banter. This is the second book in his “Lock In” series. It can be read on its own, but “Lock In” was great, too, so why not read it first?

Both books are mysteries in a sci-fi setting. In this world, 1% of the global population has Haden’s syndrome — a condition where the person is “locked in” to his/her own body. A number of technologies have been developed to support this population — implantable neural networks that link their brains directly to the outside world to humanoid personal transport units (called “threeps” after C-3PO) and an online universe called “The Agora.”

In this installment, FBI Agents Chris Shane (himself a Haden) and Leslie Vann (a female version of the crotchety senior detective persona) tackle a difficult case: the physical death of a Hilketa player during a game in which the play is all via threeps and should be no danger whatsoever to the human player. Hilketa is a (very weird to me) game played by decapitating a targeted player and carrying his / her head across the goal line.

I’m happy to say that Scalzi is back in top form. This is only the second book published after he signed a huge multi-million dollar, multi-year, multi-book deal with Tor. The first book published after the contract was Collapsing Empire — the only Scalzi book I have ever disliked (and I’ve read them all) — so I’m quite relieved that he is back on track.

Great writing and pacing, plenty of plot twists, and generally difficult to put down. I started in the morning and finished as I went to bed (only put it down briefly when I was grudgingly dragged outside to help shovel dirt into the new tomato planter). This is accessible to all readers — similar to Andy Weir’s books (The Martian; Artemis) but funnier, more inventive, and offers more exploration of the cultural and political impact of the technologies in addition to the scientific-technical angles.
