A thief's good deeds are never done.

Loch and her crew are determined to stop the ancients from returning to reclaim the world they once ruled, but the kidnapping of a friend throws their plans awry. When a desperate rescue turns into a shocking reunion, the ancients return and seize power. Determined to stop them, Loch and the group look for a way to close the gate to the ancients' world, but this time, they find themselves up against an enemy that has insinuated itself into the highest ranks of the Republic. Cruel, cunning, and connected, the ancients target the crew's families and histories, threatening to tear friendships apart.

If that weren't bad enough, Loch must deal with her treacherous assassin sister, her turncoat ancient friend, and a daemon who has sworn to hunt her to the ends of the earth. In order to save the Republic and pull off her largest con ever, Loch will need her friends...and maybe her enemies too.
