A huge international corporation has developed a facility along the Juan de Fuca Ridge at the bottom of the Pacific Ocean to exploit geothermal power. They send a bio-engineered crew–people who have been altered to withstand the pressure and breathe the seawater–down to live and work in this weird, fertile undersea darkness.Unfortunately the only people suitable for long-term employment in these experimental power stations are crazy, some of them in unpleasant ways. How many of them can survive, or will be allowed to survive, while worldwide disaster approaches from below?

First in a series of three, very very good. I was unaware that this was a trilogy, but was happy to find out it’s a series that’s been completed, so now I can look forward to reading more adventures of psychotics under the sea.
