Blake Crouch, Wayward

Wayward is the second book in Blake Crouch's Wayward Pines series. It's as readable as the first, if less mysterious: we learn the truth about the town in book one. In this outing Ethan Burke becomes integrated into Wayward Pines and learns more about the resistance movement, locals who aren't happy with the way things are run by the powers that be. The book ends on a cliffhanger, and I've already started reading book three.
