Tremors (Earthquake #3)
T.A. Webb

Unfortunately for Charlie, just when things start looking up, they always manage to crash land right in front of him. This time, his darkest terror comes true and one of the most important people in his life is missing. Charlie doesn't know what to do—surrounded by his fast growing group of friends at Mountain Shadows and his loved ones, Charlie can't seem keep it together.
Just in case a missing person wasn't enough to tear him up, his old demons are clawing at him for their pound of flesh. How does a man deal when tremors threaten to shake the very foundation of his life? And if he falls, can anyone put Charlie Turner back together when he breaks?
