Pretty Little Liars book #8 Wanted.

You might think that this is the last book in the pretty little liars series but its not, Its only the 8th book. Basically because it been a few weeks since I read this book I don't remember what happened so this will be the quick version. So Ali came back as Courtney, demented twin, who really was pretending to be Ali for years and was really friends with the girls. She was the one who was murdered, not Ali. Ali came back for revenge, which she didn't quite get when she tricked the girls, and tried to kill them all including Melissa. everyone except for Ali survived, or so they thought, which you will find out in the next book. Also, Hanna's dad is running for senate. Spencer's parents are getting a divorce. Aria gets worried when her new boyfriend Noel warms up to courtney. And Emily had a feeling that it was really Ali coming back for her.
