DARK LIFE

The worldbuilding of countless eco-thrillers serves here as the setting for a classic Western. A Western, that is, with plankton instead of cows, harpoons instead of six-shooters and submarines instead of covered wagons. Ty lives below the ocean, in a future in which water levels have risen and Topsiders live cramped together in unbearable conditions. Undersea, any brave settler can stake a claim and build a huge homestead. Ty was born down here, and he loves it. When he encounters freckle-faced Topsider orphan Gemma, he revels in showing her his world, from inflatable houses shaped like jellyfish to beautiful schools of swordfish. If only they weren’t in danger from the villainous Seablite gang that keeps attacking homesteads! This caper features a slew of Western standards—the crabby old doctor (“Doc”), the saloon filled with bandanna-clad thugs, the posse of furious citizens—and a few plot twists keep the tension high. A thrilling conversion of the classics to one of our newer frontiers. (Science fiction. 10-12)
