《天使與魔鬼》是《達文西密碼》的「前傳」哈佛大學符號學家羅柏特‧蘭登首度登場！

描述蘭登羅浮宮那趟重要造訪的一年前，發生於梵蒂岡城的冒險故事，一場異教與信仰、宗教與科學的戰爭。

　　故事敘述想以科學證明神確實存在的物理學家李歐納度．威特拉在公布他的重大成果「反物質」前夕遇害，不但眼珠子被挖掉，胸膛還被烙上一個神祕的印記。蘭登發現這個印記正是「光明會」（Illuminati）的標記，全世界最古老、最有權力的魔鬼教派遺失已久的符號。而威特拉製造出來的「反物質」，是人類所知最具威力的能源，一公克的反物質所蘊藏的能量，等於二十噸核彈──跟投在日本廣島的那顆原子彈一樣大。埋藏在地下五十公尺的「反物質」被偷走了，這種高度不穩定的物質，將會拯救世界，抑或是用來製造出有史以來最致命的武器？倒數計時已經開始……

From the #1 New York Times bestselling author of The Da Vinci Code comes the explosive thriller that started it all. 
An ancient secret brotherhood. A devastating new weapon of destruction. An unthinkable target. When world-renowned Harvard symbologist Robert Langdon is summoned to his first assignment to a Swiss research facility to analyze a mysterious symbol -- seared into the chest of a murdered physicist -- he discovers evidence of the unimaginable: the resurgence of an ancient secret brotherhood known as the Illuminati...the most powerful underground organization ever to walk the earth. The Illuminati has now surfaced to carry out the final phase of its legendary vendetta against its most hated enemy -- the Catholic Church. 
Langdon's worst fears are confirmed on the eve of the Vatican's holy conclave, when a messenger of the Illuminati announces they have hidden an unstoppable time bomb at the very heart of Vatican City. With the countdown under way, Langdon jets to Rome to join forces with Vittoria Vetra, a beautiful and mysterious Italian scientist, to assist the Vatican in a desperate bid for survival. 
Embarking on a frantic hunt through sealed crypts, dangerous catacombs, deserted cathedrals, and the most secretive vault on earth, Langdon and Vetra follow a 400-year-old trail of ancient symbols that snakes across Rome toward the long-forgotten Illuminati lair...a clandestine location that contains the only hope for Vatican salvation. 
Critics have praised the exhilarating blend of relentless adventure, scholarly intrigue, and cutting wit found in Brown's remarkable thrillers featuring Robert Langdon. An explosive international suspense,Angels & Demons marks this hero's first adventure as it careens from enlightening epiphanies to dark truths as the battle between science and religion turns to war.
