Opening paragraph.......

     "The unicorn lived in a lilac wood, and she lived all alone.
She was very old, though she did not know it, and she was
no longer the careless color of sea foam, but rather the
color of snow falling on a moonlit night.  But her eyes were
still clear and unwearied, and she still moved like a shadow
on the sea."

Peter S. Beagle,  The Last Unicorn
