Zer0es by Chuck Wendig

 

This is a kinda older Wendig novel--it predates his recent turn to more purely Horror subjects--and it's a little ... weird. There are some real body-horror moments in it, and some bits about loss of control and/or self, but it plays mostly as like a technothriller.  Wendig apparently has a past dealing with people on the technological fringes, and he seems to have enough of a grasp of what the hackers in the novel are doing to convey it without getting supertechnical about it. There's at least one moment that had me smacking my forehead (Wendig should have done a little research ...) but I got past it. I think he's gotten better as a novelist, but this is pretty good.
