In Heaven Corp, Bridges has created a solid sci-fi post-apocalyptic set-up. It's original, with lots of cool details that sci-fi fans will eat up, and deals with compelling class/social issues in a serious but not melodramatic or exploitative way. I liked the second book better than the first (technically it's a prequel) mostly because I found the central relationship more satisfying (as in hot.) It also helped that the overall plotting more assured. I do wish Bridges would do more with demons since I find them the most intriguing of the different groups and so far they have been underutilized.
Bottom Line: I am always in the market for good M/M sci-fi, and this well-written series definitely fits that bill.
