One of my hobbies is writing fanfiction. Specifically, Cristina/Owen "Crowen" from Grey's Anatomy.
I just loved this pairing so much that I started writing to fill in the gaps. If they were butting heads onscreen or not communication clearly, I could write a story where they work things out.
I had some little vignettes in my first story "Six Times That Owen Says Thank You to Cristina" and people told me that they wanted to know about what happened in between. Specifically, how did they become parents to the unnamed daughter at the end?
So I wrote "The Twenty-Four Months Before" to explain what happened in the twenty-four months before their daughter, Chloe, was born.
