Haku lives a busy life in Yamato, the imperial capital, and peaceful times have stretched on long enough that they feel permanent. Then one of his reliable companions senses something wrong. She steps forward — a woman of clear intelligence, sharp judgment, and the instincts of a chivalrous thief — and begins pulling at a thread that, once loose, threatens to unravel something deep and rotten at the center of the capital. Haku is not remotely enthusiastic about getting involved. Unfortunately, this is where the curtain rises.
