There's more to fear than frostbite and endless night beneath the frozen tundra. Cartographers may have mapped the frozen desert, but Billy Henderson is determined to be the first one to bring it to life on canvas. He turns his artist's eyes to the horizon, but fate has other plans for him. The HMS Adiona's mission was clear: brave the northern wastes, map a sledge route, and resupply the exploratory crew's base camp. Instead, they stumble upon the remnants of the HMS Atreus-a ship long lost to ice and time. Captain Isaac Scott's hopes for a rescue mission are dashed when he discovers something far older and more sinister than a shipwreck. Captain Scott doesn't believe in ghosts, but he's at great risk of becoming one.
