Eight Letters

Caitlin was used to living in abandoned buildings, or derelict houses.
She didn't expect much out of life.
All she wanted was a better life for her brother, and eight letters.
Sam was a successful architect on his way to the top of the industry.
The last thing he needed was a relationship with a woman in charge of her little brother.
And, what the hell were the eight letters all about?
