The Lost Paradise

The fifth elemental has been unveiled. Vita's memory of her reaction lingers just outside of her reach, Adrian's past holds him prisoner, and guardian Lucas Sawyer is now an enemy to his people.
With the prophecy coming into fruition, Dr. Guyer's desperation for the philosopher's stone grows in a most violent way. When Annie's well-being is threatened for the sake of the stone, Dos turns to the only source he can think of for help: the angels themselves.
