A deep-dive into human behavior in an epic story of science, society, sex, and survival, from T. C. Boyle, the acclaimed, bestselling, author of the PEN/ Faulkner Award–winning World’s End and The Harder They Come. It is 1994, and in the desert near Tillman, Arizona, forty miles from Tucson, a grand experiment involving the future of humanity is underway. As climate change threatens the earth, eight scientists, four men and four women dubbed the "Terranauts," have been selected to live under glass in E2, a prototype of a possible off-earth colony. Their sealed, three-acre compound comprises five biomes—rainforest, savanna, desert, ocean, and marsh—and enough wildlife, water, and vegetation to sustain them. As the Terranauts face increased scrutiny and a host of disasters, both natural and of their own making, their mantra: "Nothing in, nothing out," becomes a dangerously ferocious rallying cry. With characteristic humor and acerbic wit, T.C. Boyle indelibly inhabits the perspectives of the various players in this survivalist game, probing their motivations and illuminating their integrity and fragility to illustrate the inherent fallibility of human nature itself.
