Book Three of The Lord of the Rings brings about many changes for the members of the now-broken Fellowship. A lot of this book feels like atonement for past mistakes -- for Boromir, he has paid with his life; for Aragorn, he seems desperate to discern the correct path forward; for Theoden, he has finally been freed from Grima’s influence; for Saruman, the Ents have brought about his well-deserved destruction. And Gandalf has returned against all hope!
