INSTANT #1 NEW YORK TIMES BESTSELLER • The world’s most celebrated thriller writer and author of The Da Vinci Code returns with his most stunning novel yet—a propulsive, twisty, thought-provoking masterpiece that will entertain readers as only Dan Brown can do.

Robert Langdon, esteemed professor of symbology, travels to Prague to attend a groundbreaking lecture by Katherine Solomon—a prominent noetic scientist with whom he has recently begun a relationship. Katherine is 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. But a brutal murder catapults the trip into chaos, and Katherine suddenly disappears along with her manuscript. Langdon finds himself targeted by a powerful organization and hunted by a chilling assailant sprung from Prague’s most ancient mythology. As the plot expands into London and New York, Langdon desperately searches for Katherine . . . and for answers. In a thrilling race through the dual worlds of futuristic science and mystical lore, he uncovers a shocking truth about a secret project that will forever change the way we think about the human mind.

Critic reviews

“Intellectual fuel. . . . [The Secret of Secrets is] a wistful testament to the power of the printed word.”The New York Times

“Like so many things that are insanely popular. . . . Brown’s thrillers look easy to imitate but aren’t. He shatters dramatic moments into shiny, irresistible shards. . . . Dan Brown clearly had fun writing his new book. It’s contagious.”The Washington Post

“A master of the brainy, twisty thriller. . . . [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

“A new Dan Brown book has the ability to make you happy about inclement fall weather so you have an excuse to just stay home and read. . . . The story is so riveting you’ll want to clear your calendar.”USA Today

“Brown’s talent for assembling research is also evident in this novel’s alter ego as a guidebook to Prague, whose history and attractions are described in great and glowing detail. . . . There’s no shortage of action, derring-do, explosions, high-tech torture machines, attempted and successful murders, and opportunities for split-second, last-minute escapes. . . . A standout in the series.”Kirkus Reviews


Praise for Dan Brown


“Dan Brown is the master of the intellectual cliffhanger.”Wall Street Journal

“Brown is a master of the breathless, puzzle-driven thriller.”Richmond Times-Dispatch

Editorial Review

The wait is over
After nearly eight years, Dan Brown returns with another thrilling addition to his legendary Robert Langdon series. This time, the professor is in Prague to attend a lecture by noetic scientist Katherine Solomon—a woman he’s also newly dating. The action kicks off quickly with a murder and then a disappearance. From there, the gripping plot spans both continents…and consciousness. Brown’s talent for immediately sucking you into the plot has only strengthened in his near-decade off, and the science explored—along with Brown’s disclaimer at the top of the book that all science and experiments you’ll hear about are real—is chilling. Performed by series narrator Paul Michael, I can safely say The Secret of Secrets was worth the wait.—Katie O., Audible Editor
