**"So riveting you'll want to clear your calendar."--_USA Today_**

Robert Langdon, esteemed professor of symbology, has traveled to Prague to attend a groundbreaking lecture by Katherine Solomon--a prominent noetic scientist with whom he has recently begun a romantic relationship. Katherine is on the verge of publishing a breakthrough book that contains explosive scientific discoveries about the nature of human consciousness . . . revelations that threaten to disrupt centuries of established belief.

When a brutal murder catapults the trip into chaos, Katherine suddenly goes missing--and her manuscript disappears. Desperate to find the woman he loves, Langdon embarks on a thrilling race through the mystical landscape of Prague, ruthlessly hunted by a powerful organization and a chilling assailant sprung from the city's ancient mythology.

As the action expands to London and New York, Langdon plunges into the dual worlds of futuristic science and historical lore--navigating a labyrinth of codes and symbols . . . and finally uncovering a shocking truth about a secret project that will forever change the way we think about the human mind.
