The Doomsday Club: Detention can wait. Saving the world comes first!

Conan swallowed hard. The creature stood taller than the archway, a silhouette of darkness against the spiral of light behind it … And it looked directly at him. Jack and Conan's friendship is officially dead. Stuck in detention with Yash and Jerry after an all-out brawl in the toilet, it’s a terrible start to sixth class. And that’s before they witness a monstrous beast step out of a portal outside their school. When it wanders into the crumbling mansion across the road, where the sinister Mr Kilroe lives, the boys follow. They have to investigate, right? Unlocking Mr Kilroe’s secrets is only the beginning. Because there’s more than one otherworldly horror hiding in that house and confronting it will put Jack and Conan in mortal danger – that’s if they don’t kill each other first!
