When an apocalyptic catastrophe decimates the land, a lucky few escape to sea. 1,003 survivors make their home on a souped-up cruise ship called the Catalina. After sixteen years, the strain begins to show in a floating world of distrust and shifting allegiances.

Esther is a young mechanic who wants to prove herself, and she’s willing to take risks in the name of progress. But when the fresh water tanks explode, endangering the lives of everyone aboard the Catalina – it’s all Esther’s fault.

With only a little water left, the crew of the Catalina must use its last fuel to sail for help. They head to an unknown seabound metropolis called the Galaxy Flotilla. The inhabitants of the Galaxy are keen to parade their lives of luxury, but what do the saviors really want in return for their warm welcome? And what is really going on below decks?

When disaster strikes again, Esther must fight to save the lives of her friends aboard the Catalina before it’s too late.
