Light Through the Window

When Ellie first started at college, thinking her high school concerns
were behind her, she expected the biggest issue of the new semester was
avoiding being embarrassed by her professor of a father. But, when a
strange group of students showed an unnatural interest in her, she's
forced to dust off that special set of skills they had taught her at
boarding school. With her new friends, Ellie searches for information on
the group, trying to subvert their plans before they came for her. She
wasn't expecting where the trail would lead her, or the disaster waiting
to happen.
