Picked the book up today based on the recommendations here and I got halfway through it while getting my oil changed. So far so good.
At about the halfway point-
I find the storyline interesting if a little implausible. (Implausible meaning the legal aspects and political machinations not the existence of super-powered beings.)
I dislike the writing style's excessive use of sentence fragments and the too frequent use of street lingo to which I am not familiar. The 'hood' language wouldn't bother me as much if it were coming from a character, but it's from the narrator's POV, which means either it's Soledad 'talking' and it's unclear or I'm so completely out of touch with modern language changes that the slange has to be 'translated' slowly in my head which takes away some of my enjoyment of the book.
Some of the character names that the super-powered community took were too ethnic. I found it disharmonious to try to imagine someone adopting the nom de guerre of Nubian Princess, or Social Worker. On the other hand, a lot of the names were quite clever and very in genre. Nightshift and Bludlust being two strong examples. I suppose in a minor way it reflects my feelings that all the good names are taken. After over sixty years of men in spandex in the print media, a lot of the clever handles are already under copyright. (One experiences much the same trouble with a new screen name on AOL.)
Based on what I've read so far, I recommend buying the book. I normally only purchase softbacks, but was glad I made the exception in this case. Those Who Walk in Darkness has been the most interesting book I've read this year.
