Pretty little liars: How does A know everything that happens to the girls right now?

That is a very good question. In the books, the identity of the first A was revealed after Hannah was hit by the car in the parking lot. The reason that A knew all of the secrets then was because she had found Alison's old journal with every secret that Aria, Hannah, and Emily had contained in it. Now, I am not so sure how A is figuring everything out. My guess is that A is a very good spy, has someone working for them on the inside of the Pretty Little Liars friends that is close with all of them, or is working with one of the Pretty Little Liars themselves. I read the books and the TV show is obviously changing things up so people who read the books don't know whats coming next. The A situation in the books was VERY different from the one in the series.

A knows everything.
