Madwand (Changeling Saga # 2)
The sequel to Changeling is a much darker novel filled with ominous imagery and prophesy. Much is made of the fact that Pol is a "madwand" who learned magic by trial and error rather than through formal training, and forces seem to conspire to send him down a dark path like his father. It is such a shame that Zelazny did not live to write the third book of this series.
