"You ask me what Light is, Lux? Light is everything. Every single thing. The very fabric of our world is made up of this force - people, trees, the chair I am sitting on, this pen I am writing with. Few can access this Light, control it. You are one."

Huge Monsters roam the land, smashing towns to splinters. For centuries, energy-wielding Light Hunters battled the creatures, rescuing the townspeople of Daven from a terrible fate. Then, a single, disastrous mistake turned the people against Light. Now, this powerful and ancient force is mostly gone, all but a memory.

Lux Dowd lives in a clock repair shop with his ill Grandpa and the old man s live-in carer, Miss Hart. Although he might seem to be a normal 12 year old boy, Lux has a secret: not only can he wield Light, he might be the finest Light-healer the world has ever seen. But when Lux uses his power to save his best friend Maya after she is mortally injured in a terrifying monster attack, his Light draws a strange, shadowy figure to town, one who would use Lux s powers for evil.

He is rescued from the stranger s clutches by Miss Hart, who reveals to him that she is one of the last of the undercover Light Hunters tasked with watching over Lux. After a dangerous air ship journey to the Light Hunter HQ, Lux begins to learn the Light Hunter ways and form a bond with his new squad of apprentice hunters. But before he can settle, the Hunters receive a warning about an upcoming Monster attack near Lux s hometown. The Monster that destroyed his family is back.

Lux and his new friends find themselves in a race against time to locate the Monster and stop it before it can destroy the town. But is the Monster the real terror, or is there a greater danger lurking in the shadows, waiting for its moment to strike?
