While this doesn't knock declare off as my favorite tim powers book, this one is more straight forward about his technique. The structure was more bare, closely following campbell style monomyth. There were no allusions about the fact that these were gods operating in vegas.
There was some pretty undigestible homophobia in the book. It was a character flaw, but felt like it was written in the 70s, rather than being set in the 70s.
