I've had it scribbled on my book

She had already achieved the life that she wanted.

Well, almost.

After the tragedy in their lives, Chrysanthe had began a new relationship with her half brother that used to be hostile and distant to her. She works for a coffee shop and lives with Jethro. One day it just happened that she resigned to her job and started a new one being a writer. Her name made noise just on her first try and their situation kept that way her; being a successful writer, and Jethro; being madly in love with his girl and in his sister, until she began to notice things from her stories happening in reality.

And in addition her stories just happened to be tragedies...

Stories that ends either with death or death.
