My, oh Maya! Mimi, Papa, Christina, and Grant really get in over “skulls” in this Mexican hat dance of a mystery set in the Yucatan Peninsula. When they go to explore ancient Maya ruins, “number” clues seem to abound! But what is someone trying to lead them to…or wary from? Snakes…human hearts…a wall of skulls…human sacrifice? How creepy can you get, the kids wonder. But in searching for clues, they encounter the wonder that is Mexico and find themselves laughing at things they never thought could be funny—all along the way!
