Grit of Berth and Stone: The First Book of Chasmaria - Chasmaria Chronicles

Banished for a foolish mistake, sixteen-year-old Grit scorns the loss of her home, her honor, and her only ally. Only the weak worry about such things. But war is brewing all across Chasmaria, and as a group of rebels pull Grit into their ranks, she begins to question what strength, courage, and honor really look like. When faced with a horrible truth about herself, Grit must either fight her way back to Thresh or live with the blood of the innocent on her hands.
