His father was the last natural werewolf. His uncle may be a vampireTrey thought he was an ordinary teenager. Then he meets a mysterious stranger, Lucien Charron  luminously pale, with eyes that seem flecked with fire, and skin that blisters in sunlight ... yet heals unnaturally quickly.

Being transported from a care home to an opulent riverside penthouse is the least of the changes Treys life undergoes that night. In a single moment, his familiar existence is turned on its head and torn apart. Like so much else is soon to be...

The luxurious flat is, in fact, the beating heart of a sinister empire, built on the powers of the netherworld  teeming with werewolves, vampires, sorcerers and djinns.

It soon becomes clear that Trey himself  and the power within him thats roaring to break free  has a key role to play in a conflict that will shake the world. But Trey has his own battles raging within him. Is he a boy ... or is he a beast?
