Kernel Fleck's a lonely child. He's always been different -- he can see strange patches of light in the air around him. Other kids think he's mad. But when he manages to link some of the lights together, he creates a window into another universe, and disappears for several days. When he returns, his memory a blank, his panicked parents whisk Kernel and his younger brother, Art, away from their home, off to an isolated village, to start a new life.

One year later, Kernel is enjoying himself. Life is good. Until one day a crazy old woman summons a demon. The beast slaughters many of the children, then kidnaps one of them and retreats back to its own universe. The child it has kidnapped is Art.

Can Kernel find the courage to step through the window after the demon in a desperate attempt to rescue his brother? And if so, what wonders and terrors will he discover in the crazy, barbaric universe of the evil, twisted Demonata?!?

Hell's Heroes, the 10th and final book of The Demonata, starts just after the events of book 9. Grubbs bids his uncle Dervish an emotional goodbye, then returns to the world beyond with a blind, captive Kernel, to take the fight to the demon armies which are crossing more and more frequently. But he knows that his true foe is waiting for him in the universe of the Demonata. And he is also fairly certain that Bec has pledged herself to Lord Loss.

When Grubbs finally decides to face Lord Loss on his home turf, it is the start of the final ever war, in which the fate of our world and universe will be decided once and for all. The stakes have never been so high. The cost of failure has never been so deadly. And the three parts of the Kah-Gash have never been so fractured.

With heroes like this, who needs enemies?!

Demon Apocalypse is set directly after the events of Book 5. Grubbs Grady is trapped on a plane with demons and seems doomed to die. Salvation comes from an unexpected quarter, but soon Grubbs wonders if he might have been better off perishing on the plane!

Grubbs becomes a reluctant assistant to an ancient magician and sets out on a life fighting demons. He finds himself unsuited to the job, but when the lives of those he loves most are put at risk, he must try to face his fears and come to terms with his magical powers.

But the world is poised on the brink of an apocalypse. All seems doomed. The Demonata are on the verge of winning the centuries-old war with mankind. If Grubbs is to save his loved ones, he'll also have to save the world. And that's a big ask for a teenager who hates magic and is still worried that he might turn into a werewolf!!!
