1. For Tonight We Might Die

It’s a new term at Coal Hill Academy, and students are preparing for their Autumn Prom. But when the school comes under attack from the monstrous Shadow Kin, four alienated students must form an unlikely alliance to defeat them. Charlie, April, Ram and Tanya, assisted by their physics teacher Miss Quill, are now charged with a great responsibility by the mysterious alien known as ‘The Doctor’: to guard against the creatures of nightmare, who want nothing more than to find a way through to Earth and take it for their own. And this incursion is only the beginning…

2. The Coach With The Dragon Tattoo

Following the tragic events at the Prom, a devastated Ram isolates himself from the other three as he struggles with his new reality. Desperate to hold himself together on the football pitch, when he thinks he witnesses someone getting skinned alive he’s convinced he’s cracking up. But when Tanya, Charlie and April are all confronted with the same thing: a horrific, monstrous, skin-peeling dragon, they know that they’re under attack. The gang must pull together to fight against the monster, and try to keep Coal Hill safe.
