Aethereal's Clans — Christopher W. Wilcox

Spyder, the irreverent cyberpunk turned Head of the Guardian Science Support Staff, finds himself the de facto ambassador to the Ursars, a race of twenty-foot tall, telepathic and telekinetic purple bears. Forming unbreakable bonds with Korin, son of the Clan Father, Spyder soon finds there are some things that are worth more than your own life. Family, friends, and Clan, Spyder risks them all in a life-or-death struggle against the marauding Grays.
