The Riddle-Master of Hed

by Patricia A. McKillip

The titular Riddle-Master is Morgon, the Prince of Hed, a small, simple island populated by farmers and swineherds. The prince, inexplicably, has three stars on his forehead.

Morgon's sister Tristan discovers that he keeps a crown hidden under his bed. He explain that he won it in a riddle-game with the ghost of the cursed king Peven of Aum. When Deth, the High One's harpist, discover this, he explains that another king, Mathom of An, has pledged to marry his daughter Raederle to the man who wins that crown from the ghost.

Accompanied by Deth, Morgon sets forth to claim his bride. En route, the ship is sunk by mysterious shapechangers. Shipwrecked, Morgon loses his memory and the power of speech. When Deth finds Morgon again, after he has regained both. Morgon resolves to travel to question the High One about the shapechangers. The High One's home, located in the far north on Erlenstar Mountain, is seldom visited. As Morgon and Deth travel the length of the realm, they are repeatedly attacked by the shapechangers, and Morgon learns more and more perilous knowledge concerning the three stars and the great powers which come with them. He also comes to know personally the land rulers of Ymris, Herun, Osterland, and Isig.
