Chapter 1

AU to the series we know
Gabby grew up in Chicago but when she was accepted into the best medical school around she moved now she's back and working as an EMT. Her best friend Shay has offered the spare room in their 5 bedroom penthouse. What happens when she meets Matthew Casey. Lieutenant on Truck 81?

As usually I don't own any of the characters from Chicago fire (as much I wish to be Mrs Matthew Casey) or Chicago Fire it's self nor it's sister shows and characters (again as much as I wish I did)
