The perfect society holds the perfect killer. Dawn Sheffield is an ordinary citizen of Luna, but when an aerial accident becomes a viral meme, a series of events on the other side of Luna twist her fate and the fate of humanity. Dawn's place in the universe is altered beyond recognition, and at a terrible price. Elliot Humboldt is the second most powerful executive at the second most powerful organization in the Corporate Federation. Second place isn't good enough for him, though, and he makes his move to advance. Along the way he discovers a small mystery, with huge implications. Captain Tong Sianothai and the crew of the Pang Yu are on their way home from a routine mission near Ganymede when they are diverted to intimidate the largest corporate entity not a part of the Federation. They are one ship, against all of Luna. Even the most advanced societies have their darker members, and the post-scarcity civilization on Luna provides people with opportunities for any sort of creativity. It also provides ample hunting grounds for a sadistic serial killer.
