As the land of the Forest Dwellers is increasingly decimated by the Horde, Thomas Hunter, supreme commander of the Forest Guard, choses four sixteen-year-old recruits for a special mission--to find the seven lost Books of History that have power over the past, present, and future.

As Johnis, Silvie, Billos, and Darsal continue their quest for the four still missing Books of History, Billos makes a decision that has devastating consequences for himself and his companions, especially the devoted Darsal.

The Chosen Ones need Elyon's grace to face their greatest threat yet, but Darsal is torn between her new mission, trying to love the Horde as Elyon asked her to, and her original one, especially now that Johnis and Silvie no longer seem to be on her side.
