The spaceship, Questor, is caught in an unknown phenomenon which results in the vessel being transported far from home. Desperately low on supplies, they discover a system with two inhabited worlds where the crew hopes to find some assistance. Captain Sullivan visits the first world, Midea, while sending a small expedition to the second. By the time Jon and Manny arrive they’ve discovered the second planet is called Rhiava. However, when trying to land they find the planet is circled by an energy field which causes their vessel to crash.
Rescued and befriended by the Rhiava, Jon and Manny learn the truth about the oppression of the Mideans. The Rhiava aren’t the simple people they first appear, having strong mental skills they call Gifts. Helping the Rhiava leader, a young female called Triena, to reach safety, Jon and Manny travel across the planet’s surface. During the dangerous journey Jon and Triena become close and she is devastated when he is captured and tortured by Midean forces. Jon refuses to disclose anything and though he is finally rescued with help from Triena’s Gift, he has been hardened by his ordeal.
The Questor eventually arrives at Rhiava having learned the truth about the Mideans. Knowing that if they assist the Rhiava against the Mideans and succeed they will receive all the supplies they need, Captain Sullivan decides to help. Triena reveals some of her people’s secrets to the Questor crew and together they plan an attack on the Midean base.
