The heart-stopping adventure that began in Happenstance Found -- praised in a Publishers Weekly starred review for its "rich characterizations...well-choreographed action...and genuinely surprising twists" -- intensifies in the stunning second book in the Books of Umber trilogy.

Happenstance would like nothing more than to stay in the comfort of the Aerie, Lord Umber's spectacular cliffside home, without having to worry about the secrets of his past -- or the undetermined role he must play in Umber's desperate mission.

But adventure beckons when Umber receives two mysterious messages. One is a desperate plea for help from Caspar, the man who stole precious documents from Umber's archives that could unlock the mysteries of Hap's powers. Caspar is trapped on a forbidden island, the victim of a nightmarish curse. He is willing to reveal his secrets to Umber and Hap -- but what he demands in return may be impossible to achieve.

The second message is from an oppressed kingdom ruled by a brutish monarch, where an old rival of Umber's has stolen a cache of dragon eggs. The eggs have begun to hatch, and the question is, what do they plan to do with those infant dragons?
