If you had to pick one chapter out of all the books, which one would you read?

[Iarwain]

Of the entirity of Tolkien, I would read Beren and Luithien over any other chapter. Individually:

Hobbit: a bit hard to remember, I'll have to say Riddles in the Dark.

FotR: Strider, here is when the confusion lifted the first time I read the books.

TTT: The Voice of Saruman, such an interesting chapter, I love the title.

RotK: The Siege of Gondor, a thriller, simply put.

Silm: Beren and Luthien (of course)

UT: the Istari. I love the mystic feeling to these passages.

I suppose that's probably as far as is necessary.
