I've been waiting a long time for
Blake Crouch's Wayward Pines Trilogy to go on sale and today I paid $1.05 (for three books!) at Amazon.com. I believe it was self-pub at first but they made it into a TV series. It may have been a freebie at one point but I missed that boat. Also I'm a Canadian buying on the .com site so that price may be lower for Americans.
