The cover art for The Lost Symbol, Dan Brown’s follow-up to The Da Vinci Code, has been revealed. The novel hits shelves Sept. 15, and follows protagonist Robert Langdon over a 12-hour period. “Dan’s new novel is largely set in Washington, D.C., though it’s a Washington few will recognize,” editor Jason Kaufman said in an announcement. “As we would expect, he pulls back the veil — revealing an unseen world of mysticism, secretsocieties, and hidden locations, with a stunning twist that longpredates America.” The UK cover art was also unveiled.
