Reflections of the Past

Cassandra Alston cannot remember a single day of her life from before she was thirteen. Now she's nineteen and joining college, haunted by the death of a mother she can't remember and the absence of a father she's never met. The move away from home turns out to be more of a trial than she'd initially realized, what with a handsome stranger threatening her and old friends' loyalties being questioned. All this being made all the more confusing by long-forgotten memories choosing now to resurface.
Who is her friend?
Who is her foe?
Which is she?
