I dont know how I should thread the peices together in my book!

okay, so theres this one girl,and here is some details that I just cant seem to put together in the right way without making the first chapter 10 pages long...
She loves cats
She is obsessed with halloween
she just recently woke up from a coma the year before the book takes place and cant remember barely anything
shes going to a new school
she has a twin sister
she loves to draw
she wears halloween costumes to school(sometimes)
she dyed her hair orange and black.
shes born on halloween
shes got orange eyes
she has the highest grade in school (before she moved)
when she isnt wearing a halloween costume, she is wearing something orange and black


and thats about it for my difficulties!
