Remembered for Pierce's rich use of language, the series fell out of print in the early 90s, and began commanding high prices online.

The trilogy differs from many fantasy novels in that humans are not the focus, although in Dark Moon they play a major role.

Jan and Tek, finally adults in the eyes of the herd, pledge their love only to have their blossoming relationship interrupted by a vicious attack.

Jan and Tek confront their past while their children, gifted with foresight, help them prepare the unicorns for realizing their destiny.

When it matters the most, his father goes mad and flees from the herd, Jan crosses through the plains of the renegade unicorns, a parched desert, and finally into the realm of dragons, where he is shown the history of the terrible wyverns.
