The Last Unicorn: A Search for One of Earth's Rarest Creatures

I'm tempted to describe The Last Unicorn as elegiac, but that would be inaccurate on two counts.

First, although the extinction of wildlife accelerates, William deBuys tempers the destruction he reports with hope that the fragile situation for many animals may be rescued yet. An elegy usually mourns a death, and the "unicorn" of his tale, the mysterious horned beast called the saola, native to just the remotest corners of Laos and Vietnam, is not yet extinct.
