True Raiders

True Raiders is The Lost City of Z meets The Da Vinci Code, from critically acclaimed author Brad Ricca.
This book tells the untold true story of Monty Parker, a British rogue nobleman who, after being dared to do so by Ava Astor, the so-called "most beautiful woman in the world," headed a secret 1909 expedition to find the fabled Ark of the Covenant. Like a real-life version of Raiders of the Lost Ark, this incredible story of adventure and mystery has almost been completely forgotten today.
In 1908, Monty is approached by a strange Finnish scholar named Valter Juvelius who claims to have discovered a secret code in the Bible that reveals the location of the Ark. Monty assembles a ragtag group of blueblood adventurers, a renowned psychic, and a Franciscan father, to engage in a secret excavation just outside the city walls of Jerusalem.
Using recently uncovered records from the original expedition and several newly translated sources, True Raiders is the first retelling of this group's adventures– in the space between fact and faith, science and romance.
