I found the blurb for Dan Brown's next book:
When celebrated Harvard symbologist Robert Langdon is summoned to the William Penn statue on top of City Hall to analyze a mysterious ancient script—drawn on a calling card next to the mangled body of the head docent—he discovers evidence of the unthinkable: the resurgence of the ancient cult of the Lucifori, a secret branch of the Apache tribe that has surfaced from the shadows to carry out its legendary vendetta against its mortal enemy, the Vatican.
Langdon's worst fears are confirmed when a messenger from the Lucifori appears at Citizen's Bank Park to deliver a deadly ultimatum: Deposit $1 billion in the Apache tribe's off-shore bank accounts or the exclusive clothier of the Swiss Guards will be bankrupted. As the city braces for disaster, Langdon joins forces with the firm-thighed and mysterious daughter of the murdered docent in a desperate bid to crack the code that will reveal the cult's secret plan.
Embarking on a frantic hunt, Langdon and his companion follow a 700-year-old trail through Philadelphia's most historic libraries and venerable monuments, pursued by a near-sighted assassin the cult has sent to thwart them. What they discover threatens to expose a conspiracy that goes all the way back to Geronimo and the very founding of the Apache tribe.
Okay, I'm kidding. What I actually found was the Dan Brown Plot Generator
