But when Tearnan warships attack her coastal home and turn its narrow streets and ancient walled Quarters into a brutal battlefield, the rippling violence destroys nearly everything Cosette and her family have built.

Now a prisoner, Cosette is caught in a struggle between enemy factions intent on using her for their own ends. Her only hope of release, and of reaching her father, is to cooperate with the invaders. But as the fighting intensifies, it becomes increasingly difficult to cooperate without betraying the home-and the people-she loves, until she's finally faced with a choice she never expected to have to make.The Gray Sheep is the first book in the Lochsmith trilogy, a story of one ordinary woman's intimate experience with war and the change she makes in the trajectory of a continent-wide conflict.
