I have mentioned the wonderful Dean Street Press before, but I don't think I told you that they offer a "free Kindle e-book of the week". Isn't that the most marvelous thing!
You may go here to see what is offered each week. I am delighted to have just gotten the 2016 biography of Noel Coward!
Addendum: I read about 120 pages, and while it was pleasant enough, I must say I got a little bored and quit.
