I picked this up because it was described a being very similar in style to China Mieville.
It was - but I don't think it felt derivative at all.
It was sort of like if Mieville met Martin Cruz Smith met Philip Kerr. It may sound strange, but I don't think it's a bad thing at all.
Set in an alternate Soviet state, Vissarion Lom is a 'good' cop, who sees it as an unexpected opportunity when he's called to the capital to undertake a secret investigation. But of course - he gets into far more than he expected, and ends up questioning everything he thought he knew about himself and his society.
Higgins does a great job of creating his dark and atmospheric world, and weaving in mythological and original fantasy and science-fiction elements. (And really, just some wonderfully weird and grotesque things...) I'm impressed.
I'll be picking up the sequel... and yes, it is all too obvious that there will be a sequel, but I liked it enough that I'm deducting no points for the cliffhanger-ish ending.
