The Secret of Secrets continues the adventures of Robert Langdon, a Harvard University professor of Religious Iconology and Symbology. He has used his expertise to unravel complex historical mysteries in previous installments, including The Da Vinci Code and Angels & Demons, both of which were adapted into films starring Tom Hanks as the professor.
In this new story, Langdon travels to Prague to attend a lecture by Katherine Solomon, a noetic scientist (a field that explores the interconnected nature of reality through personal discovery and scientific inquiry).
True to Dan Brown's signature style, events take an unexpected turn when a brutal murder and a sudden disappearance place Langdon in grave danger as he searches for Katherine.
