In prison, Lisbeth Salander still finds opportunities to seek justice, saving a young woman from a gang—while becoming their new target. Yet in David Lagercrantz's second contribution to the Millennium series, Lisbeth is given new clues to her own past, and will need journalist Mikael Blomkvist to follow the leads for her. Lisbeth's twin sister Camilla certainly won't be doing her any favors, but she may hold the key to their family's connection to a sinister pseudoscientific experiment known only as The Registry.
