Aelathil is on the brink of civil war! Once pampered and spoiled as the only heir to one of Aelathil's most powerful lordlings, Callan's world has been tipped upside down by King Ramsey and his mighty dragons. Now he must join the growing resistance or watch as everything his family stood for crumbles away to nothing. After her father is mauled by one of the massive lion-men of the frozen north, Pyra must do her best to hold his seat as Lord until he recovers-all while teaching herself to control the magical spark smoldering inside her. Together, Callan and Pyra will shape Aelathil's future. For better or worse, they will stand Sentinel over the people that the King has targeted for destruction. Should they fail, Pyra's people will be buried in the northern wastes and Callan's family legacy will be turned to ash.
