Fiction by Ken Follett.
A cool spy thriller set in 1958, this story kept me guessing and really brought the Cold War /Space Race era to life.
I've enjoyed all the audiobooks I've listened to by Ken Follett. He's a rare writer who doesn't make me want to skim certain parts and get to the good stuff; every word in the story is important.
I also read recently by this author: Hornet Flight
