Later, Yacate appears to Maggie in a dream. She is convinced he wants her to return his bones to Mexico. While her parents are away on a cruise, Maggie, Will, and Sammy, her fourteen-year-old brother, travel south of the border in search of what is to be Yacate’s final resting place. Uncertain of where the bones are to be buried, the three pursue clues that ultimately lead them to Teotihuacan, the home of the gods.

There, they discover the ruins of an ancient civilization and the mysterious object that awaits Yacate’s return.
