A barnacle-crusted bronze cylinder pulled from a Mozambican shipwreck holds a secret that men have killed for—a 16th-century chart to a legendary lost Portuguese trading post and its vanished governor's treasury. Freelance salvage diver Theo Parker and historian Marta Monteiro must race a ruthless mining magnate through unforgiving bush country to reach the City of Bones first. But the real treasure may be far more dangerous—and far more valuable—than gold.
