Aria Montgomery (Book Character)

Aria Montgomery comes back to Rosewood after a long family trip to Iceland; before she left, Aria and Alison DiLaurentis discovered that Aria's father was having an affair with one of his students, Meredith Gates. Alison teased Aria about this, which was mentioned in the book, "Perfect", a few years back when the girls were having a sleepover and Aria was video-taping.

Aria begins a secret relationship with her teacher, Ezra Fitz, which comes to an end at prom; the relationship is rekindled and continues until "A" sends Aria's friend, Sean Ackard, a picture of Ezra and Aria together, resulting in Ezra's arrest after Sean calls the police.
