Caleb (a human) and Mezoke (a Sandjarr) are paired up and trained as special agents to keep the intergalactic peace. This is a controversial and historic alliance given their races’ longstanding enmity, and a lot of people are watching them. Their first mission is to keep war from breaking out between humans and Javlodes on the planet Senestam. Caleb acts as a mediator between the warring factions while dealing with an attack by Stilvulls (highly destructive insects) – and he also has to contend with his feelings for charming doctor Kim Vandersel. Mezoke is on the planet Upssal, trying to appease the Javlodes.
