In my personal opinion, Lisbeth Salander is one of the best FMC in literature. As a character, she’s been through hell, through more trauma than any one person should ever experience. It’s left her damaged but absolutely brilliant and with a moral code that is the foundation of everything she is. She is far from the typical FMC, in many ways more villainess than heroine, but the reader can’t help but be fully invested in her story, rooting for her every step of the way.
This is not a book for the faint of heart. It is deeply disturbing at times, very dark, and extremely intense. It does not shy away from the darkers parts of the world, nor should it. But it is highly intelligent, emotional, and incredibly engrossing.
