Watchers

13-year-old Will Booth is feeling terribly lonely. Ever since his dad died, he and his mum and their dog Spot are doing everything they can to cope with the feeling of emptiness that his father has left behind. On a cold, miserable Saturday afternoon Will goes for a walk and meets a tall, odd-looking man who describes his himself, and his kind, as Watchers. He tells Will that he must save his dad from great danger.
