"ALIEN KILLERS! MUTATED SEA MONSTERS! HUMANITY S LAST GASP! Months after mysterious corals drew 99% of humanity into the sea, a band of survivors ekes out a hollow existence on a remote British island.

How did these two return from the deep, when billions died? Most importantly, what is the coral and what does it want with the Earth? A creeping, psychological horror fable of a planet rebelling against its inhabitants perfect for fans of "The Walking Dead", "The Day Of The Triffids", and "Invasion Of The Body Snatchers" Surface Tension is a gorgeous and timely ecological adventure of unprecedented scope. The oceans have never seemed so threatening!"
