Of course if you read the books, A is really Mona. But in the last book Wanted, you find out that Ali was really Allisons Twin (and physco) sister who somehow switches places with ali before She meets Aria, Hanna, Spencer, and Emily. But when people find out Ali is dead, its not really Ali its the twin Courtney. So When Mona Dies In homecoming, the real Ali takes her place as A.
As of January 18, 2014, the real big A in Pretty Little Liars is Ezra.
