When Kincar, half Star and half Gorthian, decides to leave Gorth and join the Star lords, he passes through a shimmering gate of time. In this new element he encounters Star warriors, quite different from those who raised the Gorthians from a primitive feudal level, for the lords he now meets are tyranical and without mercy. As Kincar works out his destiny in this new world of time he simultaneously works out the fate of a magic stone which has been left in his care, and which will burn into his flesh until he finds the person to whom it must be delivered. Andre Norton, whose ability to extend scientific thought to the limit of imagination has won him many enthusiasts among science fiction fans, elaborates in Star Gate on the possibility of alternate destinies governed by optional changes in time. A fascinating concept, masterfully handled by the author.
