Book 6 of Stephen King's "The Dark Tower Series", Song of Susannah.
I'm not sure how familiar most people are or are not with the series. It's considered a classic but I'm unsure how widespread this notion is.
Anyway - I love it. The mythology is great, the combination of Western and fantasy is great and King's writing is superb as usual. This will be the series and the work he is remembered for, I think. I have a book and a half to go - can't wait to see how it turns out.
On deck, The Republican War on Science and a personal finance book.
