The Riddle of Stars 
(Book 1)

Morgon, Prince of Hed, wants only to rule and work the land of his birth as best he can, but he is faced by a very different challenge from that of his ancestors. The stars have marked him out and he must wander strange, foreign lands full of untamed magic, and confront riddling wraiths and mysterious harpists at the behest of the all-knowing High One. But his is a perilous quest, involving grave danger, to himself, his promised bride, his land and his people.
