It’s hard to tell when someone’s soul changes, especially when dark energy is around. One day, Henry’s father leaves for work like usual but never comes home. Left to fill his father's shoes with his younger siblings, sixteen-year-old Henry convinces his mother to book a family vacation at a remote cabin. He quickly realizes they were in a mysterious land when he and his eleven-year-old brother Moris find two strange magic horns and are thrown into a far-away universe where wizards are real and magic rules. The brothers soon find themselves smack in the middle of a wizard war between the Veneficums and the Milaculums. Both groups are fascinated by the humans . . . and the horns they carry. The boys have no idea one horn has dark magic and alters the soul of the one who carries it. They just want to get home again, but someone in the wizard world wants to use the horns’ power for dark purposes and will stop at nothing to get them. In a strange world where wizards fight each other and are not what they seem, who can the brothers trust? More importantly, how will they ever get home alive?

Never … Ever … let the Darkness get inside, or you might find the power within. Faced with Henry's new attitude, young Moris, together with his sister Maya and their mother, desperately search for a way to bring Henry back to Earth before the dark horn possesses him forever. Their journey takes them on a great adventure through the Lost Lands with unexpected discoveries. Meanwhile, Henry wrangles with the Milaculum wizard leader Bastian even as he struggles against the red horn and its dark energy for control of his soul. Can any of them stop the dark horn from consuming Henry? Can they save him?
