my independent reading bok

My book is called Perfect. A pretty little liars series. and what is going on in my book is there was this girl named Allison and she was very pretty and popular and one day she went missing and people where wondering where she went. A few months later they found her dead in Hanna's backyard and it was crazy. Now Allison killer is coming for Ali, Hanna, Spencer, Emily all of Allison ex-Bestfriends because they know a big secret that nobody knows about but Allison killer wont show his/her name they have the name  as A. Every text message they get from A is a bad one saying he/she will tell their secret. Emily didn't do as A said and A found a picture of Emily kissing another girl and put the pictures around the whole school. She was so embarrassed when she got to school everybody looked her up and down. Spencer on the other hand got nominated for this writing competition because of this essay that she didn't write she took it from Allison old stuff. She turned it in and the teacher nominated her for the competition and A found out about it and A  said Spencer better do as he/she says or A is going to tell her secret to everybody. Hanna big secret is that she knew that her father was cheating on her mother but didn't tell A said that he would text a picture of Hanna and her father and her fathers new girlfriend having dinner together and that would ruin Hanna friendship with her mother and her brother. Ali big secret is that she knows who A is and her ex bestfriends don't know she know. If Ali tells who A is then A is going to tell that Ali was  the one who told A  all of their secrets. That is what I read so far in my book.
