Exactly the kind of complex, action-packed, scientific thriller you would expect from Dan Brown. The focus on noetic research is fascinating, and the tightly woven perspectives make for a read that is hard to put down but gives you a lot to think about. While some characters felt a little flat, and the book was a bit drawn out, I really enjoyed it!

Summary

The world's most celebrated thriller writer returns with his most stunning novel yet—a propulsive, twisty, thought-provoking masterpiece that will entertain readers as only Dan Brown can do.

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.

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.
