Off Pitch (New York Stars #1) by Ashley Bow:
 
Fake it ‘til you make it, baby… but what happens when faking it starts to feel real?

Harlow Pierce runs a blog for her favorite baseball team, the New York Stars, but she needs to expand—New York City ain’t cheap, and there’s rent to pay. She needs something big to help her get noticed… and she finds that in the league’s favorite broody pitcher, Knox Spencer.

“Fort Knox” is known for his grumpy attitude and cold demeanor. He’s the league’s best pitcher with a disdain for any of the fame that comes with that. With an endorsement deal on the line, Knox has no choice but to open himself up to someone… and thanks to his agent, that someone is Harlow Pierce, his shiny, new fake girlfriend.

With their undeniable attraction to each other, this season should be a breeze.

But when emotions deepen and past trauma rears its ugly head, Harlow and Knox learn how easy it is to blur the lines between real and fake. Can they hit a home run or will they strike out?
