Warhorse 

The Tampy aliens’ living spaceships are far more powerful than humanity’s non-biological technology. Can they—and should they—be tamed?Throughout the universe, space horses are among the most coveted of species. They are starfaring creatures with telekinetic abilities, tamed and controlled by the Tampy aliens—who aren’t willing to share their understanding of the creatures. Despite diplomatic government intervention, human poachers are determined to capture and control the giant beings. With a tenuous peace treaty in place between the Tampy and humans, the first jointly helmed space horse will undertake its first mission. But will the two races be able to work together—or will their peace break down into all-out war?
