This book is a novella.

“JUSTIN WAS HELPLESS on the ground, not able to move a muscle as the dark figure came over him. The sinister being paused a moment, raised his arms toward the boy, and then as the demon's face glowed, radiant energy shot from it's hands. Justin could feel his body being enveloped in the painful rays, and could feel his soul going numb. As his brain fought the torturous pain, his mind went back to the events of the last week that brought him to this agony. In a small part of his mind he could see himself sitting safely in his home reviewing his school books and, for a brief moment, re-lived it.” Thus begins the journey of Justin through the world of fantasy.
