The setting is Southern California. It is the late 1980s in a world where the Axis won World War II. The occupied Western United States are now the United States of Japan (USJ), and the occupiers rule with an iron fist despite the appearance of a happy and prosperous nation. The secret police tortures and “disappears” people at the least hint of treason against the Divine Emperor. Beniko Ishimura is an underachieving Captain in the Imperial Forces working as a censor for videogames. Ten years earlier, he took part in quelling a major revolt in San Diego, and now those events are coming back to haunt him.
Oh, and there are giant robots. This is seldom a bad thing.
Even without Mr. Tieryas’s explicit admission in the afterword, it is obvious that this book was heavily influenced and inspired by The Man in the High Castle, down to the dissenting material showing an alternate reality that is in fact that of the reader; one where the Allies won and the world is very different. The world-building is excellent, showing a dystopian USJ that is struggling economically and socially while all criticism of the regime is harshly punished. The cruelty of the torture and death inflicted by both USJ agents and dissidents is graphically described to the point of making the reader squirm, but in this world such things are sadly normal.
The story is somewhat opaque in the first half of the book, but things rapidly clarify towards the end, when flashbacks to the San Diego revolt and events in the present converge. Themes of betrayal, loyalty and forgiveness are strongly emphasized in a strong ending.
