"A work of genuine literary merit . . . What Mr. Kesey has done in his unusual novel is to transform the plight of a ward of inmates in a mental hospital into a glittering parable of good and evil."
–The New York Times Book Review "[A] brilliant first novel . . . a strong, warm story about the nature of human good and evil . . . Keysey has made his book a roar of protest against middlebrow society's Rules and the invisible Rulers who enforce them."
–Time "The final triumph of these men at the cost of a terrifying sacrifice should send chills down any reader's back. . . . This novel's scenes have the liveliness of a motion picture."
–The Washington Post "An outstanding book . . . [Kesey's] characters are original and real. . . . This is a tirade against the increasing controls over man and his mind, yet the author never gets on a soap box. Nor does he forget that there is a thin line between tragedy and comedy."
–Houston Chronicle
