It's a small change in our history: imagine that the Japanese made contact with the Aztec Empire.nbsp; Instead of small-pox and Christianity,nbsp; they brought an Imperial alliance, samurai ethics, and technology.nbsp; By the time of these books, the Emperor in Mexico City rules not just the entire planet Earth, but a growing interplanetary Empire.nbsp; But the Galaxy is not a hospitable place, and there are other powers, both new and very very old, who would stop the spread of the power in Anuhuac. nbsp; A weapon of the Old Ones, from the time of the First Sun, has been found in a region of space.&nbspIt must be investigated, then&nbsptamed or destroyed to keep it from the hands of opposing powers.nbsp; Gretchen Anderssen, freelance archeologist and specialist in First Sun artifacts, has been hired by her old mentor Green Hummingbird, agent of the Mirror Service, to join him in the study.nbsp; They will be joined by old friends, and some old enemies as well.
