On my Kindle I am reading "It can't happen here" by Sinclair Lewis which imagines a fascist takeover of the US. It was inspired by Lewis' opinion of Huey Long and Father Coughlin.
Also I am reading "11.22.63" (50 years ago this year) which is a Stephen King one where he goes back in time to stop Oswald doing his dastardly deed.
And "The Time Machine Did it" by John Swartzenwelder (who wrote my favorite Simpsons episodes) which is corny science fiction and feels like it might have been written over a weekend but has some very witty jokes.
