Nizhoni Begay struggles a bit. She manages to embarrass herself on the basketball court, watches out for her younger brother Mac because her mother left several years previously, and has to deal with her father's long work hours. When he is approached by Mr. Charles, who wants him to relocate the family to Tulsa, Nizhoni is concerned about moving but also because Mr. Charles is a monster! A statue of a toad, Mr. Yazzie, that she has in her room comes to life and reinforces this information, and is very helpful. Her father doesn't believe that Mr. Charles wants to kill her because she can see monsters, so when she and her brother are called to the office at school, Nizhoni decides to run away, getting help from her best friend Davery (who helpfully has a credit card!). Mr. Yazzie sends them off to try to find Spider woman, who can help get their father back from Mr. Charles. In order to request a map from her, there is a quest to get four jewels from the Four Sacred Mountains, as described in a song that a Diné Holy Person has given them. When they finally meet the Spider Woman, she tells them that a map is not needed, but Nizhoni still needs to travel the path to the sun in order to free her father. Along the way, there are trials and tribulations, she briefly loses both Mac and Davery, and she finds someone from her past who is able to help. In the end, will her skills and powers as a Hero Twin be enough to send Mr. Charles and his monsters back and keep the world safe?
