Wolf Island, by Darren Shane

This is part of the Demonata series, and this shows the other side of the main situation problem from the book before it,   Death shadow. In death shadow you are Bec, one of the main characters in whole series so far, and you go to the Demonata world to try to expose the greatest threat ever. But in Wolf Island, you are Grubbs, another main character, who stays on earth to try to find who has been controlling the werewolfs and why they are after his family!

Grubbs has to go through the struggle of keeping focus on the main mission and not letting his emotions cloud his mind and control his actions. The reason that he is so emotionally attached to this mission is because, all of the werewolfs... Are his family members! He might not know all of them, but seeing what they have been being used for frustrates him and it seems he will need all the help he can get to try and keep him from doing something very gerastic.
