Books by David Sage

On the Summer Solstice, through the hole in the medallion Juan and Sophia see an ancient stone mason at work, but when they get to Great Grandfather he has no explanation of what it means. Now the twins begin to learn about Great Grandfather's past, an astonishing story which neither of them had any clue about.

Juan and Sophia, 12 year old twins in southern Colorado, learn that they are the latest in a series of heirs to an ancient silver medallion. Adzul, the first book of the series, is the story of their ancestor who first comes into possession of the medallion and risks his life to save it.
