Strange Roads — Jennifer Quail

What do an ex-Navy test pilot and a Senate staffer have in common? Nothing, really, except for being the two most powerful Mages born in decades. And none too soon, because the forces of evil are gathering to take over the world - or, at least, Washington D.C. Elaine Gates and Alan Graves are the Lady of Wind and Water and the Lord of Earth and Fire, or so the mysterious Mark Valentine and his equally-enigmatic partner, Nadia Julian say. Sparks literally fly when these unlikely allies join forces in a race to find a mysterious artifact before the forces of evil do, and to discover the key to their destinies . . .
