The Runaway King By Jennifer A. Nielsen

A kingdom teetering on the brink of destruction. A king gone missing. Who will survive?
Just weeks after Jaron has taken the throne, an assassination attempt forces him into a deadly situation. Rumors of a coming war are winding their way between the castle walls, and Jaron feels the pressure quietly mounting within Carthya. Soon, it becomes clear that deserting the kingdom may be his only hope of saving it. But the further Jaron is forced to run from his identity, the more he wonders if it is possible to go too far. Will he ever be able to return home again? Or will he have to sacrifice his own life in order to save his kingdom?
The stunning second installment of The Ascendance Trilogy takes readers on a roller coaster ride of treason and murder, thrills and peril, as they journey with the Runaway King.
