Year of the Pig is a personal account of one avid hunter's pursuit of wild pigs in eleven American states. Mark Hainds tied his mission to the Chinese calendar's Year of the Pig in 2007 and journeyed through longleaf forests, cypress swamps, and wiliwili forests in search of his prey. He used a range of weapons—black-powder rifle, bow and arrow, knife, and high-powered rifle—and various methods to stalk his quarry through titi, saw palmetto, privet hedge, and blue palms.

Introduced pig populations have wreaked havoc on ecosystems the world over. Non-native to the Western Hemisphere, pigs originally arrived in the southeast with De Soto's entrada and in the Hawaiian Archipelago on the outriggers of South Pacific islanders. In America feral hogs are considered pests and invaders because of their omnivorous diet and rooting habits that destroy both fragile native species and agricultural cropland.

Appealing to hunters and adventure readers for its sheer entertainment, Year of the Pig will also be valuable to farmers, land managers, and environmentalists for its broad information and perspective on the topic.
