On his first trip to London to stay with his glamorous aunt and uncle for Christmas, Ivo Moncrieff steps off the train and stumbles into a nightmare. As he is waiting on the tube platform, a stranger thrusts a mysterious object into his hand, desperately muttering some unfamiliar words to him. On-board the tube moments later, the carriage next to Ivo's is overcome with panic and when they enter the next station the passengers disembark to find that the stranger's body has been brutally dismembered.

Ivo guesses that perpetrators must want the object, and if they find out he has it, he will be their next target. But the attack on the tube is part of a larger scheme to bring chaos to the heart of London. As the capital seems in danger of sliding into anarchy, Ivo faces a race against time to break the ancient power of the Liberators, a power that has lain dormant for centuries but now threatens to destroy society itself. Philip Womack has written a gripping and thought-provoking tale that entertains at the same time as it explores what it means to be human and to be free.
