This is a gritty book, and I'd squarely place it in the older YA section. The main protagonist, Shreve, is certainly an antihero. I found myself cringing often at his language/choices, AND YET he and his partner (in crime? in heroics?) are honestly so lovable. I I sure do enjoy a solid morally "gray" character, I find. I'm looking forward to reading the rest of the series, as the paranormal/mystery of it all is well done.
