Sometimes I want to punch that smirk off Atlas McCallister's pretty face. He's cocky. A troublemaker. A pain. And, unfortunately, my stepbrother. We've been fire and kerosene since our parents got together, and to keep from exploding into fistfights, we've used challenges, dares, and bets to battle out our differences. Our past bets have been a little inappropriate—scandalous, even—but Atlas's latest bet has gone too far. Do I really believe if he loses, my straight stepbrother is gonna mess around with a guy? And not just any guy: me, his rival and nemesis?

Curtis “Launchpad” Larkin’s career as an astronaut has had its share of ups and downs. Alternately lauded as the single-handed savior of NASA and condemned as a reckless, hot-headed bully, Curt has been through the wringer of public opinion and come out on top. When he embarks on his final mission with NASA, Curt figures there’s no curveball that life has left to throw him.

It's official: my step bro is the biggest himbo ever to himbo. He's a massive blond beefcake with a soft heart and an over-eager smile. The mere sight of him incites a shaking hot rage in me. He's everywhere. He's around me all the time. So sweet and gentle that it makes me feel wild. I see him and smell him everywhere. When I can't see him or smell him, I hear him. The wall between our bedrooms is paper thin. I can't help it—I hear what he does in his room when he thinks he's alone. I hear everything.

My loser high school friend never deserved him anyway. If I’d had the chance, I would have locked Remy down years ago. Only, when the party leads to a drunken kiss, going on their honeymoon, and sharing their marital bed, I have to say, I’m not entirely sad that their wedding went up in flames.

Ever since we met two years ago, Eden Burkehammer has made everything better. The big defenseman sets me at ease. He’s a beast on the ice—brutal and physical—but when it’s the two of us, he turns to me with these unexpectedly soft brown eyes. This gravelly laugh that makes my whole body smile. And yeah, I might have thrown a glance his way a time or two in the steamed-up locker room showers—you know, just curious. But he’s my best friend. My teammate. Roommate. I don’t want to mess with that. Just the thought of losing him sends a cold zap the full length of my spine.
