Dead Locked — Amy Saunders

Imogen Bell dishes publicity for a team of explorers, and she just can't resist a good pirate tale. So when her boss is murdered, Imogen dares to defy her anti-lore boyfriend and joins forces with his nemesis in a hunt to find treasure worth killing for. If she doesn't want to end up in Davy Jones' Locker, Imogen must trust the clues of a dead man and crack open a centuries-old mystery before her opponent does it first.
