Matt and Em Calder are no ordinary seventeen-year-old twins. They are Animare, an ancient order of artists who can bring drawings to life and travel in time through paintings. They work for Orion, an intelligence agency that protects the secrecy of their order.
The work is rarely dangerous. Until they are sent to rescue Rémy, a teenage boy sleeping rough in London. Rémy’s mother has been murdered – and now her killers are hunting him. For he is a Conjuror, the last descendant of an ancient bloodline that can change reality with music. His song gives him powers beyond those he ever dreamed… powers that could be deadly if they fall into the wrong hands.
