On a summer vacation to Mexico, popularity-obsessed Kat ends up on a teen adventure tour where she meets Nando, a young Mayan guide (who happens to be quite a cutie). As they travel to different Mayan ruins each day, Nando tells Kat his original legend of Muluc, a girl who lived in the time of the ancient Maya. The dangerous, dramatic world in which Muluc lived is as full of rivalry, betrayal, and sacrifice as Kat s world at middle school. And as she makes new friends and discovers treasures in Mexico, Kat begins to question her values and those of her friends back at home."
