Ok, I admit, I am a big Lord of the Rings geek. I LOVE these books. I've also seen all three movies and enjoyed them immensely. So, it seems right to have this humble series as book(s) of the day.
The series of course, is really introduced in The Hobbit, but one can easily read the LOTR trilogy without having read The Hobbit.
The story, for those unfamiliar (though it's hard to imagine world without people who have at least a little knowledge of LOTR) revolves around the "young" hobbit Frodo and his fellowship who go on a journey to rid Frodo of the one ring in the fires of Mordor. There are so many twists and tales and amazing plot points throughout, that it would be impossible to detail everything in these stories. So, if you've never read these books, get to a library and check them out! You won't regret it.
