All the time travelling over the years has caused the very walls of space and time to become thin. There’s something pressing in on the other side, something waiting for its chance to kill everyone and everything, to bring us all into Shadow. Four Coal Hill School sixth formers will face their own worst fears, navigating a life of friends, parents, school work, sex, sorrow and possibly the end of existence.
When monsters invade Coal Hill, four students form an unlikely alliance to defeat them.
A dreadful new monster threatens the school, and the gang must unite to fight against it.
London is infiltrated by an eerie alien and the team must battle to save Tanya.
As April's connection to Corakinus strengthens, a sinister invasion begins.
April must confront Corakinus as the others try save the Earth from extinction.
Trapped in detention, dark truths emerge and fractures form in the friendship group.
With the gang trapped in detention and out of the way, Miss Quill accepts Dorothea's astonishing offer: to help remove the Arn from her head, and to reclaim her freedom. Alongside Ballon, an imprisoned shape-shifter, Miss Quill travels in a metaphysical engine and is taken to impossible, extraordinary and dangerous worlds, collecting materials in preparation for her life-changing procedure. After an emotional encounter with her surgeon and a nearly-fatal operation, Miss Quill must find a way to return to Earth: transformed and ready for war.
Facing an impossible choice, our heroes must use all they’ve learnt to save Earth. But how far are they prepared to go? And will they have to pay a price? Unable to recover from the truths they have faced, the gang has splintered. Liberated from enslavement, Quill prepares to take her revenge. But they must reunite when the Shadow Kin return, raging a ruthless, unrelenting war. Resolute to claim April’s heart and Charlie’s weapon, Corakinus threatens to kill their families until he has what he desires – and the friends must fight to prevent him. This time, not everyone will make it out alive.
