Infiltrating a pirate ship disguised as a boy is easily the most dangerous thing Brigid O'Cullane has ever done. But she has no choice if she ever wants to regain the treasure map that belonged to her dead father. Her father's closest friend Liam Lynch holds the map now and he may well have had a role to play in her father's death. When the dangerously sensual Liam catches her, he hints at secrets her father never shared--a double life of danger and wonder, magic and horror. Now she has no choice but to work alongside a pirate she cannot trust.
