Jun Ironway—hacker, con artist, and occasional thief—has gotten her hands on a piece of contraband that could set her up for life: proof that implicates the powerful Nightfoot family in a planet-wide genocide seventy-five years ago. The Nightfoots control the precious sevite that fuels interplanetary travel through three star systems. And someone is sure to pay handsomely for anything that could break their hold. Of course, anything valuable is also dangerous. The Kindom, the ruling power of the star systems, is inextricably tied up in the Nightfoots’ monopoly.

That’s what they told him, anyway. The only actual members of Unity that he’s ever met are Boreau, a giant snail who seems more interested in plunder than spreading love and harmony, and Boreau’s human sidekick, Neera, who Dalton strongly suspects roped him into this gig so that she wouldn’t become the next one of Boreau’s crew to get eaten by locals while prospecting.

There are only three real powers in the Spiral: the corporate power of the Trust versus the Union's labor's leverage. Between them the Guild tries to keep everyone's hands above the table. It ain't easy. Branded a Guild deserter, Jal "accidentally" lands a ride on a Guild ship. Helmed by an AI, with a ship's engineer/medic who doesn't see much of a difference between the two jobs, and a "don't make me shoot you" XO, the Guild crew of the Ambit is a little . . . different.

In Daretana’s greatest mansion, a high imperial officer lies dead—killed, to all appearances, when a tree erupted from his body. Even here at the Empire’s borders, where contagions abound and the blood of the leviathans works strange magical changes, it’s a death both terrifying and impossible. Assigned to investigate is Ana Dolabra, a detective whose reputation for brilliance is matched only by her eccentricities.
