If Janet Chow hadn't been such a jerk to everyone at Sewanhaka High, they might have voted her Most Likely to Succeed. Twenty-plus years later, life hasn't turned out how Janet expected. She's rudderless, her career in journalism crashed, burned, and buried. How did it come to this?

But then one day, Janet recognizes her mortal enemy from high school—Pam Kowolski! Somehow, Pam's become America's manic pixie sweetheart, an online psychic predicting the end of the world. Pam's rich, hawt, and famous, meanwhile Janet looks...middle aged. How did this happen? How did Pam Kowolski steal Janet's life?

Janet knows the truth: there's no way a dumb ass like Pam earned her success. She's lying about her powers. The world isn't ending. Pam's a FRAUD. It's time for Janet to wake up and claim what's hers by writing an article that TAKES PAM DOWN. But to reveal Pam, she's got to dig deep into their shared past. There's bad stuff back there, scary stuff, and the more Janet learns, the more she worries: what if Pam Kowolski is right?
