In Canadian author Watts's intense, beautifully written conclusion to his Rifters trilogy (after 2004's ▀ehemoth: ▀-Max), Lenie Clarke, the near-psychotic, bio-engineered woman who loosed the deadly organism known as ▀ehemoth on an already environmentally compromised world, resurfaces from the ocean's depths to discover who's behind continuing efforts to destroy all life on Earth. Together with Lubin, a bio-engineered man who's a highly efficient killer, Clarke discovers an America that has been devastated, not just by ▀ehemoth but by attacks from heavily fortified, high-tech enclaves whose rulers will stop at nothing in a futile attempt to contain the out-of-control organism. Worse still, the battle is apparently being led by Achilles Desjardins, a murderous psychopath who has slipped the protective psychological programming that once kept his darker impulses under control. Aided by Taka Ouellette, a guilt-ridden, second-rate physician, Clarke and Lubin strive desperately to unravel the secrets of both ▀ehemoth and Seppuku, its even more dangerous mutation. Like some adrenaline-charged fusion of Clarke's The Deep Range and Gibson's Neuromancer, Watts's trilogy represents a major addition to early 21st-century hard SF.
