In a Rush by Kate Canterbary

What’s better than a revenge date?
A revenge husband.
Pro quarterback Ryan Ralston has always known two things. First, he’s desperately in love with his best friend Emme Ahlborg. Second–and most importantly–he still has no idea how to tell her.
The marriage pact they made in their senior yearbook was the closest he ever came. Years passed and Emme forgot about their promise. Ryan never did, especially not on his thirtieth birthday.
Emme can’t catch a break. Always unlucky in love, her cheating ex is a groomsman in her best friend’s wedding—and there’s no way she’s showing up alone.
Ryan offers her the one thing better than a wedding date: a revenge husband. And he’s not just any fake husband but the NFL’s brightest star…and in need of serious reputation rehab.
Playing the part of the happy couple comes easy and soon enough, the lines between real and fake blur. They disappear altogether when there’s just one bed.
All Ryan has to do is save Emme from her ex, find her step-sister an internship, and get his wife to fall in love with him—or fumble the one thing he’s ever wanted: her heart.
