The Two Towers by J.R.R. Tolkien

This book divides its energies evenly between the events that begin to stir Rohan and Gondor as the remaining members of the Fellowship come into their bounds and Frodo and Sam's journey to Mordor, with the help of Gollum. This time through, I was particularly struck by the foreshadowing with regard to Gollum's role in the adventures. I was also much more aware of the logic of Frodo and Sam's journey (sometimes I hesitate to start Book IV, but not this time!).
