Dan Brown himself says about the new book: „The Mystery of All Mysteries is my most ambitious novel yet, with the most intricate plot – and also the most entertaining. Writing it has been an unforgettable journey full of discoveries.“

Nihar Malaviya, global director of PenguinRandom House, states: „Dan Brown is coming out with a new thriller about Robert Langdon that will undoubtedly captivate and delight readers around the world. Alongside a gripping plot, all the other typical elements of Dan's books return in full force: codes, art, history, religion, and cutting-edge science. One of the most amazing literary heroes of our time, Robert Langdon, will travel to Prague this time, one of the most mysterious and beautiful cities in the world, where he finds himself caught up in a whirlwind of fantastic events with his new love. The Mystery of All Mysteries is Dan's best novel yet, and its release will be the biggest event in the literary world in 2025.“ 

Brown's longtime editor Jason Kaufman notes: „I am always amazed by Dan's intricate plots and prophetic ideas. The Mystery of All Mysteries reveals a fascinating world to us through completely unexpected plot twists. Classic Dan Brown.“   

And Petr Onufer, editor of Argo Publishing, who extensively consulted with the author on the manuscript of the new novel set in Prague, adds: „Dan Brown can illuminate the settings of his novels from completely unexpected angles: his novels are, in a certain sense, also fascinating guides to beautiful places. And his portrayal of Prague is among the most impressive: after reading The Mystery of All Mysteries, you will see Prague with new eyes.“

ABOUT THE MYSTERY OF ALL MYSTERIES:

The most popular author of our time returns to the scene and offers his most breathtaking work to date – an action-packed, intricate, and thought-provoking story that will entertain readers as only Dan Brown can. Robert Langdon, a renowned professor of symbology, arrives in Prague and embarks on a lecture by Katherine Solomon – a leading researcher in noetics, with whom he has recently begun a romantic relationship. Katherine is preparing to release a controversial book that brings alarming revelations about the nature of human consciousness and has the potential to overturn many beliefs that humanity has held for centuries. However, the peaceful course of their stay in Prague is suddenly disrupted by a brutal murder, plunging them into complete chaos: Katherine mysteriously disappears along with her manuscript, and Langdon becomes the target of a powerful organization and a mysterious attacker who seems to have emerged from ancient Prague legends. And while the story shifts to London and New York, Langdon desperately searches for Katherine… and answers. During a frantic chase through the ghostly world of futuristic science and ancient mythology, he uncovers a shocking truth about a secret project that will forever change our perception of the human mind.
