I like sci-fi alright, though I mainly read mystery and fiction, and the first half of the book got me pretty excited about the author. The beginning is exciting and interesting, kind of Blade Runner in terms of future-tech, but then it (Spoiler alert) turns into a zombie novel. I hadn't read any of his work before. I was thinking of recommending the book to a friend who's really into Neal Stephenson's work. But then... zombies? Really? That was a disappointment.
Beyond that (hey, if you're into zombies, you'd be cool with this), I did like the writing alright - it was a little repetitive and predictable (if I hadn't read a hundred times about Glee's "flat eyes" I might have been surprised to see her return zombie-style), but definitely readable. It is a second novel of a series (I think), so I did feel a little like I jumped into the middle of something, where other authors may have given a little more background. I did like all the action in the book, which reminded me a little (a very little) of Lee Child's Reacher series.
