Children of Zion

"In the epic showdown, Noah's people, the children of Zion, find themselves trapped between two warring tribes of dragon worshipers, both set on the destruction of the city of light, Zion. Although still only a boy, the fate of his family and his people rests firmly on Noah's shoulders. He must step out of his father's shadows and overcome the darkness by slaying the king of dragons as the tribes plunge into battle. But slaying the dragon king requires Noah to be in the light, and that light seems nowhere to be found." -- from teddekker.com.
