The children of Anubis:

Twenty- two years ago Samantha and Deanna Summer's lost their mother to a mysterious and demonic force. In the years after, their father, Joshua Summer's taught them about the paranormal evil that lives in the dark corners and the back roads of America... and taught them how to kill it... Samantha and Deanna travel to Indiana, to investigate a murderer that could be the work of a werewolf. But they soon discover that werewolves aren't the only things going bump in the night. The town is also the home to a pack of jakkals who worship the god Anubis- carrion eating scavengers who hate werewolves. With the help of their friend Jacob, the sisters must stop the werewolf- jakkal turf war before it engulfs the town- and before the god Anubis is awakened.
