I always feel guilty about disliking any of King's work. However, I disliked this one because the characters were not developed enough for me to care one way or the other. It reminded me a lot of Dean Koontz's "Intensity," and Intensity, also available on Audible, is a better buy in this case. Unless you want a quick, brainless story to get you through a car ride or a run at the gym.
This is the first King audiobook I've listened to that I hadn't previously read. An awesome read that kept me captivated! The reader of the book did an excellent job.
