The quiet librarian

Summary: "Hana Babic is a quiet middle-aged librarian in Minnesota who wants nothing more than to be left alone. But when a detective arrives with the news that her best friend has been murdered, Hana knows that something evil has come for her, a dark remnant of the past she and her friend had shared. Thirty years before, Hana was someone else: Nura Divjak, a teenager growing up in the mountains of war-torn Bosnia--until Serbian soldiers arrived to slaughter her entire family before her eyes. The events of that day thrust Nura into the war, leading her to join a band of militia fighters, where she became not only a fierce warrior but a legend--the deadly Night Mora. But a shattering final act forced Nura to flee to the United States with a bounty on her head. Now, someone is hunting Hana, and her friend has paid the price, leaving her eight-year-old grandson in Hana's care. To protect the child without revealing her secret, Hana must again become the Night Mora--and hope she can find the killer before the past comes for them, too"--From Amazon.
