Russell Davis & Jenna Solitaire 
Keeper of the Flames [EPUB ebook] 

In the third volume of this YA fantasy series, Jenna follows her destiny to the Middle East where she must locate—and master—the power of fire. From the moment Jenna Solitaire discovered her destiny as a Keeper of the Boards, she has travelled the world to protect it from the hidden powers of the elements. So far, she has already located the Board of Air and the Board of Water. Now, together with the handsome and mysterious Simon Monk, she journeys from the searing desert of the Middle East 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. Her nemesis Peraud is hot on their trail. And he’s more determined than ever to claim the two Boards Jenna already possesses. But 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.
