I'm on my third reading of the single-volume version of The Lord of the Rings. It's taken a month of reading on the toilet, but I'm currently two chapters away from Return of the King.
This all started with a chance re-reading of The Silmarillion a couple months back, followed by a re-watching of the extended edition LOTR movies, and a smattering of Unfinished Tales. I'll probably take on The Hobbit graphic novel and then grit my teeth for an extended foray into Unfinished Tales and finish with Children of Hurin. I might chell the War of the Ring books after seeing the new movie this winter.
