The Mysterious Messenger

In Beverly high there were these five girls that were best friends Amanda, Alison, Emma, Stephanie, and Heather. Alison was like the only popular one out of all the her best friends. They decided to have a Labor Day party because it was almost Labor Day. They planned it out and they invited their parents to go to it because it was like a special party for them. The girls assisted and they played games and laughed because they were having a good time in the party. They all felt like if they were sisters because they trusted each other. They shared their experiences and their dirty little secrets. Including the really bad ones. Then Alison went to the garage to get presents and she does not return because something bad happens to her. The girls and their parents try to find her, but they can't. The girls separate. 2 years later they reunite because they get messages from this person called "A". The messages he/she sends are threatening ones and the girls try to find out who "A" is. They all think that "A" is Alison because Alison's name starts with an A and because she is the only person that knows their secrets. Then they find Alison again and she tells them that she is really afraid of this one person that threatens her. Could it be that she is afraid of "A"? Alison mysteriously leaves and gives the girls no clue of where they could find her again. The girls search everywhere for her, but they don't find her. They come to this old man's shack in the woods and he gives them advice of how to find Alison. Will they be able to find Alison and bring her back? This is my first story so it should not really be that great as most of you guys might expect it to be, but I think it is a good one.
