Short stories are fun and portable. While Stephen King is great, his 11.22.63 comes in at 866 pages (and that is the Kindle edition), a bit difficult to read in one reading session. Take along an eReader with a few books of short stories loaded. You can fill the down time created by your less than punctual friends with reading. You might even feel a sense of accomplishment by finishing something. Here is a collection of short stories I liked; they appeal to those who want to read on the dark side.
I received this book through the Library Thing Early Reviewer program in return for a review. I read it in a PDF format. It is a bit harder to read that way; I would have much preferred the mobi format.
