From Goodreads:

"A Hollywood millionaire with a terror of death, whose personal physician happens to be working on a theory of longevity - these are the elements of Aldous Huxley's caustic and entertaining satire on man's desire to live indefinitely.

With his customary wit and intellectual sophistication, Huxley pursues his characters in their quest for the eternal, finishing on a note of horror. Written soon after Huxley left England and settled in California, the novel is his examination of American culture, particularly what he saw as its narcissism, superficiality and obsession with youth. It also raises pertinent philosophical and social issues."
