When a battered spellbook tumbles from his attic and tears open a gateway to another realm, an ordinary teenager named Simon is dragged into a magical world alongside his faithful dog Chippy. Stranded in this unfamiliar land and narrowly evading a pack of hungry goblins, Simon learns that his arrival is no accident—he's been summoned to undertake a perilous mission to free the wizard Calypso from the clutches of the dark sorcerer Sordid. With only his wits and an unexpected aptitude for magic to rely on, Simon must navigate this strange new world and confront forces far beyond his comprehension.
