Beholder's Eye - Julie E. Czerneda
This was quite an enjoyable read. The first couple chapters are awkwardly crammed with exposition, telling us what our hero Esen-alit-Quar is and how the mechanics of her shape-changing work, but after that it settles into a lively adventure story, with an appealingly warm interspecies friendship at its center. Czerneda's taken a bit of trouble over coming up with interesting alien species, too, including the herd-thinking Ganthor and the touch-oriented Ket. Whatever shape she's in, Esen is a sensuist, reveling in the impressions of her senses, and Czerneda enjoys describing things that humans wouldn't be able to experience.
