Fiery Bonds for an Earthling

On Earth, locked in eternal snow, where under the cold light of the stars everyone survives as best they can, Kayla is fighting with the last of her strength against the invaders. But the forces are unequal: the battle is lost, and the girl is taken prisoner. Only the settlers of this world are not the kind to give up when the lives of their loved ones are threatened. For the sake of meeting her sister, Kayla is ready to risk everything—even to burn herself on the scorching heart of the fire commander.
