The Angry Angel (Sisters of the Night #1)

In a distant age of brutal chaos, young Kelene is her family's salvation. An exquisite, golden-haired child just entering womanhood's embrace, she is blessed -- and cursed -- with a great gift: the protection of the Militant Angels. For most of her fourteen years, God's messengers have guided her, shielding Kelene, her parents, her brothers and sisters from the horror and devastation visited upon their neighbors by the bloodthirsty Ottoman hordes.
