The Heir's Army: Book Two of the Sapphire Dagger Quartet

Stranded far from home by injuries and the onset of winter, Charlie of Windsong receives a letter alleging that her father, believed dead for several years, is not only still alive, but living close by in Shala. Despite considerable doubts, Charlie can't resist investigating, and she decides to set aside her search for the sapphire dagger to try to find her father instead. What starts as a search for one man quickly involves her in something much larger and more complex than she could have imagined. 

Trading solitary travel to join a band of political rebels, Charlie now finds herself at the center of a movement that will not only take her across Shala and beyond, but will also potentially change the course of history in the Eastern Lands forever. Charlie has come to enjoy the independence and self-reliance she has learned since leaving her sheltered life at Windsong to travel alone, but committing to a cause larger than herself requires putting aside her own desires for the success of the mission. As she struggles to contribute to a group that views her as an outsider, she must fight to hold onto her autonomy and determine where her loyalties lie.
