Bashed, by Barbara Marquardt
As school closes for Christmas, a teacher doing her best in a failing and chaotic high school is knocked down by an abusive student and locked into a biology storage area. As the small room has a sink and some food stored for lunches and prep periods, she is only in danger of spending two horrible weeks dieting in a cold room with no toilet or bed or much else beyond obsolete books and broken equipment. Waiting and hoping for rescue, she creates order and routines, trying to make the best of her time and solitude. As she ponders her life and career, which are about to change drastically, she does not realize that the student will tell a different story in which she was to blame.
