Because of moments like those: I was looking for something else entirely (specifically, information about religion in Tlatelolco for a minor character in book 3), and happened upon an awesome tidbit of information related to the time period, which will fit great into the novel.
Research is made of awesome.
PS: apparently, book 3 is now listed on amazon, with a Sept. 1 2011 release date (and no title). Good to know while you’re writing it…
EDIT: OK, according to AR this is an erroneous listing, and the book will *not* be released on Sept 2011. Phew.
