The people of the town of Springside had been witness to sightings of strange and unexplained lights in the summer sky. The question everyone asked was, were these sightings caused by something from beyond their world? Carrie Williams and her brother Sean had experienced a similar occurrence when they were children, but they had very different memories of that time. It seemed to Sean that it was possible that something might be back and looking for Carrie. Now that Sean was home, he and Carrie's friends were determined to solve the mystery to protect her. Carrie knew that her blocked memories from that long ago summer held the key, but would she be able to remember in time?
