Brinley Rivers is a 15 year old student at Pacific Coast Academy, a boarding school for boys and girls in Southern California. Her best friends, Hunter, McKenna, Ashleigh, Kyle, Devin and Ella, all think she's crazy when she claims that she was visited by someone from the past. But she's not crazy, nor is she lying. On a night in the middle of October, Brinley is visited by the very first time traveler; but they don't bring good news. There's something strange going on at PCA in the past, and everyone was told Brinley could fix it. So the great Brinley Rivers goes with the time traveler to PCA in 2007, to solve The Mystery Of PCA; and maybe meet some new people along the way. (Based on the Nickelodeon TV show, Zoey 101)
