This is nothing more than a foolish fling, with a plane ticket deciding our end date. So why are we torturing ourselves by going deeper?

Morgan: As a cybersecurity expert, I rely on reason. When every rational thought told me getting engaged was a mistake, I not only agreed, I fled - to a temporary consulting gig in Sydney, as far from Boston, and my boyfriend, as I could get. I didn't plan on falling fast and hard for a man I was never meant to have.

Luke: I grew my family's billion-dollar chocolate empire by refusing to play it safe. After a fierce and sexy American consultant sweeps me off my feet with her kung fu moves, I'm all-in on a risky affair. She says she can't stay Down Under, but I'm giving her a billion reasons not to leave.

Despite family ties pulling Morgan home and Luke's duties anchoring him in Australia, they can't keep their hands off one another. As their hearts become entangled, they face an impossible dilemma - between logic and longing.

With the very real prospect of living half a world apart, will they figure out how to be together, or is it time for a billion last goodbyes?
