A new entry in the critically acclaimed Caine Riordan science fiction series by three‑time Nebula nominee Charles E. Gannon! Science fiction on a grand scale. Prequels Raising Caine, Trial by Fire and Fire with Fire were all Nebula Award finalists. Charles E. Gannon is also the winner of the Compton Crook Award.

Caine Riordan, fresh from serving as envoy to the aliens known as the Slaasriithi, has been given yet another daunting task: apprehend raiders that are terrorizing a distant planet.

As difficulties mount, Caine becomes aware that the mission his superiors sent him to perform may not be the one they actually hope he will achieve. Which means Caine may be forced to choose between honoring a promise to friends or following orders—a choice that could ultimately put him in front of a board of inquiry. Or a firing squad.
