Mirian Raas comes from a long line of salvagers adventurers who use magic to dive for sunken ships off the coast of tropical Sargava. When her father dies, Mirian has to take over his last job, a dangerous expedition into deep jungle pools, helping a tribe of lizardfolk reclaim the lost treasures of their people. Yet this isn't any ordinary job, as the same colonial government that looks down on Mirian for her half native heritage has an interest in the treasure, and the survival of the entire nation may depend on the outcome.
