This is what I understood from the books:

Courtney and Ali were twins and BFFs. But then, they began to become enemies. One day, the mom and dad saw Courtney almost killing Ali, so they decided to send Courtney to the preserve (AKA mental people hospital or something like that). But what they didn't know was that first of all, Ali forced Courtney to do that to get her in trouble. Second of all, the accidentally sent Ali to the preserve instead of Courtney, because Courtney pretended to be Ali and they looked (almost) the same. Ali tried to tell everyone that she was ALI, not Courtney, but nobody believed her. So, when Ali came home for vacation, she killed Courtney. When the mom and dad could not find Courtney (who they had thought was Ali the whole time) they (obviously) blamed it on Ali (who they though was Courtney). So, they sent Ali back to the preserve, again. Ali became A and Courtney was dead. BTW not to spoil it, but Ali's boyfriend, Nick, is the A who sends the 4 girls the texts. I found out in the book Toxic.
