I went with
The Age of Daredevils myself. It sounds really interesting, even though I don't read much non-fiction.
I was a bit tempted by
The Unbroken Line of the Moon, but I have concerns about that one. First off there's so
many names and groups mentioned in the summary alone that I had trouble keeping track (the fact I was sleepy didn't help). Second, it's a series and book two won't be out till next year. If it's a trilogy, that means it'll be at least two years to find out the whole story.
At least the selections were much, much better than the Kindle for Samsung selections this month. Those were just dreadful.
