Blood Song? Yeah, it was good; I'm reading the next one. It's just that there were a lot of tortured sentences, garden path sentences, homophone errors, and so forth. Basically stuff that should have been caught by a half decent editor. I also feel that Ryan was kind of doing a dark fantasy by numbers, patching on cool ideas rather than starting from a cohesive, unique, and compelling effort of world building. He mostly pulls it together at the end, though, and you can tell that it's starting to gel, giving him ample room for improvement in subsequent books. But still, it was an enjoyable read.
Compare that to the Southern Reach trilogy. Each book was beautifully written, sleek and modern, and inarguably original. All that, though, and it left me cold. I finished Acceptance not entirely convinced that it wasn't all a waste of time. Reading Annihilation, I was reminded a lot of Lost, and that assessment didn't prove too far off. The thing is, as many problems as that show had, at least it made me care about the characters, and I'm apparently one of the few that was OK with the ending. I can't say that about Southern Reach.
