The Girl With the Dragon Tattoo features extremes of friends and enemies. Mikael Blomkvist and Erika Berger's twenty-year friendship is the cornerstone of their lives, yet it isolates others they might also try to befriend. In contrast, Lisbeth Salander and her guardian, Nils Bjurman, begin a hideous showdown that brands them enemies for life. When Salander and Blomkvist finally meet in Chapter 18, both of their lives are dramatically changed. For all the wars waged in the novel, at its heart there are decent people struggling to figure out love, friendship, trust, and all that good messy stuff.
