In a trailer park called Adjacent, next to the Folsom Energy Plant, people have started to vanish, and no one seems to care. At first Lady Di and her best friend, Tom Jones, barely notice the disappearances—until their beloved math tutor, Mrs. Clarke, is abducted, too. Mrs. Clarke has left them clues in the form of math equations that lead them all over the trailer park, through hidden tunnels under "Mount Trashmore," and into the Folsom Energy Plant itself, where Lady Di and Tom Jones and a gang of other misfits uncover the sordid truth about what's really happening there.

About the author

Benedict Carey, a former Los Angeles Times writer and current New York Times science section writer, was a math and physics major in college, so he knows his geometry. Hoping to ignite a passion for math in his own kids, Benedict decided to craft a smart and action-packed story for middle-grade readers that uses math lessons to solve the mysterious disappearance of their math tutor. He and his wife and children live in a suburb of New York City.
