So the main Character name is Ashtashia Devis. She is in grade school (this books starts from when she is of 1 class and ends when she leaves the school in the end of 3 class). Ashtashia is from a Wealthy family but she didn't said this in school. She was bullied mentally a lot due to her silent personality and because the bullies were jealous as she gets higher grades. She couldn't do anything about this because the teachers in this school paid no attention to the condition of the students. She didn't said this to her parents because she doesn't wants them to worry about her. Then a whole lot of drama happens. In end her sister transfers to other school as her sister also didn't liked the school so she also transfers to that school fortunately and the story ends.
The brief of the whole series is that Ashtashia runs away from her home to achieve her dreams as pop star. You can say a runaway star story. And basically this is a very dark and depressive story with few funny stuff also.
