Melaia sends Trevin into enemy territory to retrieve the third harp she needs to restore the stairway to heaven and free the angels trapped in a human world. But an assailant wants Trevin dead, an unknown traitor is passing information to the invading enemy army, and the Firstborn immortal has vowed to destroy all three harps, along with anyone who stands in his way. Separated, Trevin and Melaia try to keep their faith, hope, and love for each other alive. From the land of Windwing horses to the mountaintop lookouts of Stargazers, from the blight-ridden fields of the Camrithian homeland to the night-dark caverns of the Under-Realm, they face the ultimate test: What are they willing to sacrifice to restore the stairway and save their world? Will they lay aside their love for each other? Will they give up their future together?
