在《達文西密碼》（The Da Vinci Code）還未竄上暢銷榜之前，Dan Brown的舊作一直不能算是熱門書。Angles & Demons可以說是《達文西密碼》的前傳，也是他所有的書中科幻味最重的一本。他的主角也就是出現在《達文西密碼》中的符號學家蘭登，只不過蘭登這次要破的案子，可不是跟名畫有關的，而是瑞典實驗室的一位頂尖的物理學家被謀殺，他的突破性成果——一個能量可與核能相比的物質被偷，抽絲剝繭竟然發現這是一樁與梵蒂崗有關的陰謀……

Angels & Demons is a 2000 bestselling mystery-thriller novel written by American author Dan Brown and published by Pocket Books. It revolves around the quest of fictional Harvard University symbologist Robert Langdon to uncover the mysteries of a secret society called the Illuminati and to unravel a plot to annihilate Vatican City using destructive antimatter. The book uses the idea of a historical conflict between science and religion, particularly that between the Illuminati and the Roman Catholic Church. The novel introduces the character Robert Langdon, who is also the protagonist of Brown's subsequent 2003 novel, The Da Vinci Code. It also shares many stylistic elements with its sequel, such as conspiracies of secret societies, a single-day time frame, and the Catholic Church. Ancient history, architecture, and symbolism are also heavily referenced throughout the book. A film adaptation was released on May 15, 2009, though it was set after the events of The Da Vinci Code film, which had been released in 2006.
