Race to the Sun

From the publisher: "Lately, seventh grader Nizhoni Begay has been able to detect monsters, like that man in the fancy suit who was in the bleachers at her basketball game. Turns out he's Mr. Charles, her dad's new boss at the oil and gas company, and he's alarmingly interested in Nizhoni and her brother, Mac, their Navajo heritage, and the legend of the Hero Twins. Nizhoni knows he's a threat, but her father won't believe her. When Dad disappears the next day, leaving behind a message that says "Run!", the siblings and Nizhoni's best friend, Davery, are thrust into a rescue mission that can only be accomplished with the help of Diné Holy People, all disguised as quirky characters. Timeless themes such as the importance of family and respect for the land resonate in this funny, fast-paced, and exciting quest adventure set in the American Southwest."
