I first read The Lord of the Rings trilogy when I was about about twelve, I believe. Loved it then, and have treasured it more and more over the years. I've skimmed and re-skimmed favorite parts countless times, but only recently did I read the whole trilogy from beginning to end for a second time, out loud to my oldest son. If I had to pick my favorite book of the three, I suppose it would be The Fellowship of the Ring. I always like to revisit it in late summer and early fall, around the time of Bilbo's and Frodo's birthday and of their departures from the Shire.
