Ironcrown Moon (Boreal Moon, Book 2)

King Conrig has united the warring island of High Blenholme-but his enemies are plotting against him. Danger arises when word comes that the magical Trove of Darasilo has vanished from its secret crypt. In the wrong hands, it would seal Conrig's doom. His only ally is his childhood friend, Snudge. But even Snudge knows Conrig's greatest weakness is his lust for power--and that the Trove could be his key to acquiring it.
