The Light is the suspenseful first installment in a new trilogy by the author of the popular Pendragon series. Marsh does not have many friends and is a bit of a geek, but is extremely likeable. His character evolves over time, becoming more confident and courageous. Marsh is on his own during this haunting, as his father is out of town on business and his mother died two years earlier. The story does involve some violence. Gravedigger carries a pick and tries to kill Marsh himself or by controlling other people. This demon also terrifies some into lunacy, including a man who runs into the street and is killed by a truck in front of Marsh. It is discovered that Cooper died when a teen boy (controlled by Gravedigger) smashed into his fishing boat in the dark. Scare-sensitive readers should be aware that there is some creepy imagery, including blood that explodes out of a golden orb and attacking corpses in varying stages of decay. Marsh and Cooper's sister, Sydney, are chased by a reptilian monster and almost drown in a wave of blood. Language is relatively mild (p-ssed, h-ll, d-mn, a-s).
