I'm going to pretend you're talking about The Doors of Perception.
Even though you are obviously talking about Brave New World.
In an interview with Ron Martinetti of American Legends website, Laura Huxley called Island "the finest and final work." In Laura's opinion, "He put everything in that. Brave New World was a warning and Island was an offering."
