Can time travelers go back and stop the dragon apocalypse? Stop the total destruction of Earth? Keep the Scorch from ever happening?
When the last dragon egg is discovered and ends up in Trinity's hands, her life changes from the uncertainty of bills and whether she and Grandpa can keep their house, to can she raise a dragon?

Who can she trust? Connor the dragon hunter? Or Caleb the dragon sympathizer?
