Thomas Nelson (2007)
In Chosen, the land of the Forest Dwellers is increasingly decimated by the Horde, and Thomas Hunter, supreme commander of the Forest Guard, must choose 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. In Infidel, Johnis and the other "chosen" recruits of the Forest Guard are pulled into deeper danger as they try to secure the seven lost Books of History. And Johnis tries to rescue his mother from enslavement by the Horde, but risks betraying the Forest Dwellers.
