The Secret of Secrets: A Robert Langdon Novel
On the verge of publishing an explosive book that contains startling discoveries about the nature of human consciousness and threatens to disrupt centuries of established belief, Robert Langdon's new girlfriend Katherine Soloman is set to deliver a groundbreaking lecture on the subject when a brutal murder sets events into chaos. Soon Katherine, and her manuscript, is missing and Langdon is thrown into a desperate search for her, and for answers . . .
A propulsive, twisty, thought-provoking masterpiece of a novel, The Secret of Secrets offers a thrilling race through dual worlds of futuristic science and mystical lore.
"Dan Brown's novels move with kinetic energy, his plots are intricate puzzles shrouded in religious iconography and ancient cryptography. The Secret of Secrets is perhaps his most ambitious undertaking yet: a dense thriller that is also a meditation on the nature, and the possible future, of human consciousness.” -- Los Angeles Times
