The distant world of Russalka has no land, only the raging sea; no clear
skies, only storm clouds. Beneath the waves, the people live in
pressurised environments and take what they need from the ocean. It is a
hard life, but it is theirs and they fought a war against Earth to
protect it. But wars leave wounds that never quite heal.
Katya Kuriakova doesn't care much about ancient history like that,
though. She is making her first submarine voyage as crew; the first
journey of what she expects to be a nice, simple career. There is
nothing nice and simple about the deep black waters of Russalka,
however; soon she will encounter pirates and war criminals, see death
and tragedy at first hand, and realise that her world's future lies on
the narrowest of knife edges. For in the crushing depths lies a sleeping
monster, an abomination of unknown origin. And when it wakes, it will
seek out and kill every single person on the planet.
