Fifteen-year-old Riley knows the golden rule of a London pickpocket: never be seen. 

Having grown up on the streets, she uses her ability as an Illusionist to vanish in plain sight, picking pockets to survive.

But when she swipes a mysterious silver amulet from a stranger, her life is turned upside down. She is spotted by Fin, a homeless boy with a unique and rare gift. He doesn’t have powers; he suppresses them. He is the only person in London who can see through Riley’s illusions.

Thrown together by fate, they are hunted by Grant Ashwood, a powerful tycoon who believes that chaos is a disease that must be cured at any price. He wants the amulet, and he wants the boy.

Forced into hiding at Falconwood, a school for children with powers, Riley finds herself trapped in a game of spies and betrayal. With a traitor in their midst and Grant’s forces closing in, Riley must stop running and start fighting. To survive, she must unravel the school’s darkest secrets and forge unlikely alliances to stop the most dangerous man in London.
