Unicorn Mountain

Unicorn Mountain by Michael Bishop won the Mythopoeic Fantasy Award in 1989.

from the back of the book:

Libby Quarrels is a divorced Colorado rancher near bankruptcy; Bo Gavin is an Atlanta adman with AIDS; Sam Coldpony is a Ute Indian with a vengeful past; his daughter, Paisley, is haunted by her dead mother's ghost. Into the lives of these four fragile human beings comes a species of unicorn as beautiful and mysterious as it is vulnerable. The mythical creatures have come from a faraway place to the majestic Colorado mountains for a specific reason: someone has to do something here, in this world, to save them from a deadly plague that could wipe them out once and for all.

Together, these four very different people must face a severe test of courage and humanity as they seek to save these magical beings - and the magic in themselves - from total extinction.

Surprising, compassionate, witty, and true, Unicorn Mountain is a novel of transcendent wonder by one of our most important contemporary authors.

It's currently out of print, but amazon.com has some used copies. This book just feels so dated to me, with an air of deliberate social relevance that sounds, oh, I don't know... a bit forced to me. I'm putting this one aside for now and may get back to it when I'm more in the mood. Or maybe not.
