No, to be honest I had never even heard of it until now! I never got into the audiobooks, therefore I haven't read anything from King or anyone else that has been released only as an audio book. I guess I need to get into those audiobooks since there seems to be a ton I have missed out on. I may start 11/22/63 next, the story itself sounds great, I just need to keep an open mind while reading it and enjoy the story.
UR is available as an e-book...or a kindle book...whatever the term is. Plus...I don't believe you need an actual kindle to read it. Reason I ask is because like so much from King, there are echoes in UR or pre-echoes if you'd read it...and then 11/22/63. And yeah, put aside whatever preconceived or learned or assumed knowledge about the assassination...it's a story nothing more nothing less. There's some others...Ken...Something...Replay...another by a Shapiro not as good forget the title...plus that one from Delillo...Libra? And that one from...I forget this other's name, too...but he title is something like American Tabloid. If you're interested I can look at my have-read list, but this last American Tabloid...I think it is a 1/3 of 3 published...or maybe the final is not yet published. I guess they call that a trilogy. Sounds Greek, hey? Trilogy. Sounds like something about Homer. But that one takes the assassination story and tweeks the...or one of many of the theories abounding.
