I went in with high expectations (and not having read the short story prequel). They were met. This is delightfully horrifying--less viscerally so than Grant's Parasitology series, at least for me, but in a way that will stick with me, the next time I'm far enough out on the water that I can't see the shore. If you're a long-time Grant fan, it's worth saying: this one is more gruesome than the Newsflesh series, but not as lingeringly gory as some horror stuff by other authors can be.

As is universal (or at least nearly so?) in Grant/McGuire books, this one has people of various (dis)ability levels, of various races and orientations. It includes more of the human experience than most speculative fiction seems to, and it is better for the inclusion.

And the science is fantastic, as always.
