My name is Jenna Solitaire, and I am the Keeper of the Boards. With the elements of Air and Water at my command, I now go in search for the most dangerous Board I have sought so far—the Board of Fire.

From the searing desert of the Middle East, Jenna and Simon travel to the ancient city of Pompeii, following the clues to the hiding place of the Board of Fire—also known as the Board of the Flames. But Peraud is hot on their trail, and is more determined than ever to claim the two Boards the Keeper already possesses. Jenna must also contend with her growing attraction to Simon, who is torn by his desire for her—and his sacred duty to the Church.
