Memoirs of a teenage amnesiac

So far in my book Naomi went to a party got drunk and called her dad and he came and picked her up. She saw that there was a lady in the front seat and she smelled like flowers. She didn't know that she was her dads fiance. She wakes up the next morning and has a hangover even though she only drinked one beer and the only reason it did that to her is because she has a major head trama.
