The Hunter and the Sorcerer Publisher's Summary
A prehistoric tale of the Pleistocene...the adventures of Bru, a Hunter of the Seven Rivers Tribe, as he goes up against saber-tooth tigers, cave bears and an alien race intent on clobbering his world....
Banished from his tribe after offending the chief, a hunter named Bru stalks into the tiger-haunted hills with only his stone knife and the furs on his back, determined to find some way to appease the chief so he might return to the tribe. For if he doesn't return soon, the girl he loves will be mated to a hated rival on the night of Wyrm.
Yet Bru's plans are thrown out of kilter when he runs afoul of a visitor from another world. Bizarrely instructed in science and physics beyond his simple ken, savage Bru finds himself making a deal with the mysterious outsider that will allow the hunter to return to his people.
