We were never meant to see each other again. It was a one-night, no-names fling in Bermuda . . . until the next day when I watch her walk down the aisle at our parents' wedding and discover she's now my stepsister.

We say it won't happen again, but we give in to the temptation of "just one more time" . . . twice. We tell ourselves there's no harm in it. Given my stepdad's and her mom's rocky marital histories, it's unlikely we'll ever see each other again.

Except, a few days later, I walk into the Boston Rebels' offices to assure management that I'll focus on nothing but hockey after I missed last season thanks to an injury. Instead, I find myself face-to-face with my stepsister, Morgan, who now works for the team.

At first, we pretend we've never met and try to steer clear of each other. But it's impossible. Her friends are tangled up with my teammates. Her dad is my agent. She's everywhere: at the rink, out with our friends, and in my head.

I have every reason not to pursue her. I tell myself I'll stay away. And yet, I can't get enough of her.

So we make a deal: a secret friends-with-benefits arrangement-no feelings, no commitment.

The more I truly get to know her, though, the more I can't imagine my life without her. But forever is the one thing I promised myself I'd never give anyone again.
