Hidden in London is a legendary power. A fabled chest guards secrets more precious than gold.
But in 1666 secrets are deadly, and London is burning....

As flames ravage the city, the thief taker must track the chest into London's blackest heart, where smugglers trade and sorcerers conjure. What Charlie begins to unravel is more ancient and powerful than he ever dreamed.
But time is running out and fire is the greatest purge of all.
