The Girl Who Takes An Eye For An Eye, Lagercrantz - B

                                               This is the fifth book in the Lisbeth Salander series and the second by this author, the official successor to Stieg Larsson. It continues the story of Lisbeth, ties together pieces from previous novels  and, presumably, leaves open all sorts of future possibilities. The focus is on both Lisbeth and Blomquist uncovering a diabolical experiment involving twins. Decades earlier, a Swedish social/medical  entity separated twins at birth in an effort to study the consequences of varied child-rearing circumstances. Those who managed the experiments work diligently to hide their history and protect each other. Tie in plot lines involving unassimilated Muslim immigrants and a particularly vicious criminal and you wind up with an enjoyable, but clearly not great, addition to the series.
