From publisher blurb:
Creatures of myth, whispered in legend, lost in the mists of history—and now returned for reasons unknown to any but themselves. Such are the cavians, a race of humanoid rodents noted for their incredible psionic abilities. The cavians were exiled from Exodus for nearly three hundred years, and their unexplained return has made more than a few other races extremely nervous.Fear of cavians comes naturally to those without psionic gifts, for these rat-folk can see thoughts and emotions the way most humanoids can see color. Worse, most cavians are scions of a racial hive mind, a collective intelligence of phenomenal power.
