Trapped in a sun-scorched gibbet at Port Royal, Harwicke — known to some as "Blacktongue" — is offered a grim lifeline by the mysterious Captain Silas Rook. Trading the cage for a life of high-seas subversion, Harwicke must use his wit to orchestrate a bloody mutiny against a corrupt Quartermaster. In a world of forged articles and stolen gold, he discovers that numbers always betray, and vengeance is a debt best paid in person.

Swashbuckling. Witty. Vengeful. Piratical.
