Confinement to the secure unit of a women's prison is intended as a punishment. Instead, Lisbeth finds herself in relative safety. Flodberga is a failing prison, effectively controlled by the inmates, and for a computer hacker of her exceptional gifts there are no boundaries. Lisbeth knows she is coming closer to solving the mysteries of her early life; and even within the confines of the prison, she feels the deadly influence exerted by her twin sister. Lisbeth will stand up for what she believes in. She will find out the truth. Whatever the cost.
