The Heron kings
(Book)

After a warlord slaughters her patients, Sister Alessia quits the cloister and strikes out on her own to heal the victims of a brutal dynastic conflict. Her roaming forest camp unwittingly becomes the center of a vengeful peasant insurgency, raiding the forces of both sides to survive. Alessia struggles to temper their fury as well as tend wounds, consenting to ever greater violence to keep her new charges safe. When they uncover proof of a foreign conspiracy prolonging the bloodshed, Alessia risks the very lives she's saved to expose the truth and bring the war to an end.
