Shan, Darren - Demonata, book 2, "Demon Thief"

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?!? Find you when you read "Book 2 of The Demonata -- Demon Thief".
