Luke is just one relic away from opening the doorway back to his own world and taking his parents away from the terrors of Scream Street! But the final search threatens to plunge him into the most dangerous adventure yet. With the help of Resus and Cleo, Luke is desperately hunting for the claw of a werewolf--and in the process he learns something most unexpected about Samuel Skipstone, the author who has helped them so much on their quest. This forces the trio into making a difficult decision, made harder by the witch convention taking place on Scream Street. The sixth and final relic is almost in Luke's grasp, but will it ever be his?
