Salt

In the near future, the effects of a catastrophic solar flare have left the earth almost entirely submerged, with only the tops of the very tallest mountains remaining above water.

Moored to one of these peaks is a flotilla of ships and boats containing all of the planet's known survivors. One hundred and twenty-five souls remain, but not for long--a mysterious infection is turning the air they breathe and the water they drink into deadly hazards.

Twelve volunteers have been sent out to look for help--or even any signs of life--and none have returned. It now falls to Eva, a former cop, and Jim, the flotilla's elected leader, to keep the fragile peace among the inhabitants. Humanity is depending on them for its survival--together, can they find the answers in time?
