After reading "Ur," I'm contemplating some other Stephen King books. A lot of people seemed to read him at a formative age, and I think I missed out. And while I've tried some of his stuff in the past and been underwhelmed, the Kindle seemed like a good way to dip a toe in from time to time without too much of a commitment.
How about "The Shining"?
Kindle price? $19.25! Marked down from the digital list price of $35.
Mass market paperback price? $7.99. That's without any discount.
At least "The Stand" has only a 90 cent difference between the paperback and the Kindle versions, with the Kindle having the advantage of being the cheaper (marked down from $50!) as well as freeing one from having to carry a 1141 page tome with one for the duration.
