Denzel is just doing his homework one day when he senses he is not alone. In the corner is a weird black shape, waving its smoky black tentacles menacingly at him. Then two figures explode through his window; they are the Spectre Collectors, a secret organisation monitoring the barrier between the spirit world and ours, and preventing any hostile spirits making it across. Their leader is Doctor Quisling, a woman whose smile never quite reaches her eyes. She is intrigued by Denzel, as no one has ever been able to actually see 'geists before. She recruits him (i.e. makes it impossible for him to return home to his dads) and soon Denzel is caught up in the weird world of spectre collecting. But he senses all is not as it seems...
