The Girl Who Takes an Eye for an Eye by David Lagercrantz

Second Hand 

THE GIRL WITH THE DRAGON TATTOO LIVES ON.

Lisbeth Salander is an unstoppable force:

Sentenced to two months in Flodberga women's prison for saving a young boy's life by any means necessary, Salander refuses to say anything in her own defence. She has more important things on her mind.

Mikael Blomkvist makes the long trip to visit every week - and receives a lead to follow for his pains. For him, it looks to be an important expose for Millennium. For her, it could unlock the facts of her childhood.

Even from a corrupt prison system run largely by the inmates, Salander will stand up for what she believes in, whatever the cost. And she will seek the truth that is somehow connected with her childhood memory
