Salvage captain Tavren Ossick knows how to bring people home from dangerous water. Then the water begins to leave.
His estranged son is stranded aboard a research vessel on the exposed Atlantic floor. Tavren and six other survivors follow an ancient road through grounded ships, abandoned stations, and evidence of a danger that was deliberately removed from public charts.
What begins as a rescue becomes a struggle to protect a growing company of refugees as the world below the sea opens into a war no chart can explain.
