There's only one rule; Never fall for your best friend's sister. Definitely don’t agree to a temporary fling. I’m stuck working with Ashley Williams when I'm forced to help my mom’s catering company for the holidays. Ashley’s a firecracker, and I always love getting under her skin...but now I want her skin against mine. I want to bite that forbidden lip she’s always giving me. She wants me too but she’s been burned before and says we're only hooking up until the new year. This fling may have a deadline, but now that we're rolling around in the snow—I can't just walk away.
