What are you reading?

I am sure I will still be reading 11/22/63 by Stephen King for many more days.  It is about John Fitzgerald Kennedy and his wife both surviving an "attempted" assassination in Dallas in 1963 because someone went back in time to change history as we know it.  I am still reading, so I do not yet know how the author makes it happen.  (Read what I have already posted about the thick 880-page book HERE.)
