Over twelve novels and two collections Lydia Millet has emerged as a major American novelist. Hailed as "a writer without limits" (Karen Russell) and "a stone-cold genius" (Jenny Offill), Millet makes fiction that vividly evokes the ties between people and other animals and the crisis of extinction. Her exquisite new novel is the story of a man named Gil who walks from New York to Arizona to recover from a failed love. After he arrives, new neighbors move into the glass-walled house next door and his life begins to mesh with theirs. In this warmly textured, drily funny, and philosophical account of Gil's unexpected devotion to the family, Millet explores the uncanny territory where the self ends and community begins--what one person can do in a world beset by emergencies. Dinosaurs is both sharp-edged and tender, an emotionally moving, intellectually resonant novel that asks: In the shadow of existential threat, where does hope live?
