An evil wizard called Flagg subverts the noble Prince Peter and installs a puppet in his place, setting sinister plans in motion in Stephen King's fantasy novel The Eyes of the Dragon.
This unusual departure for horror master King was one I somehow missed when it came out in the 80s. I am glad I found it as an audio book read by Bronson Pinchot, quickly becoming one of my favorite audio book readers. It is a very credible fantasy, probably most reminiscent of William Goldman's The Princess Bride, but enjoyable in its own right. Both share a bright, funny narration that carries the story along.
For fans of King's larger body of work, there are definitely threads and themes that appear or re-appear in other novels, probably most notably The Stand and The Dark Tower series.
I checked this out from the Morrison-Reeves Public Library in Richmond, Indiana, and enjoyed it thoroughly.
