T. is a young Los Angeles real estate developer consumed by power and political ambitions. His orderly, upwardly mobile life is thrown into chaos by the sudden appearance of his nutty mother, who's been deserted by T.'s now out-of-the-closet father. After his mother's suicide attempt and two other deaths, T. finds himself increasingly estranged from his latest project: a retirement community in the middle of the California desert. As he juggles family, business, and social responsibilities, T. begins to nurture a curious obsession with vanishing species.

Soon he's living a double life, building sprawling subdivisions by day and breaking into zoos at night to be near the animals. A series of calamities forces T. to a tropical island, where he takes a Conrad-esque journey up a river into the remote jungle. Millet's devastating wit, psychological acuity, and remarkable empathy for flawed humankind contend with her vision of a world slowly murdering itself.
