A gumpy-sunshine, age-gap rom com

There are so many reasons he's going to regret that first kiss...

The problem with wanting his friend's much too sweet and innocent younger sister?

His grumpy personality doesn't work on her. She knows him too well.

But when Sara Bradford decides she wants Jason "Mac" Gordon too? He's screwed.

In the bad way. But the good way, too.

So, what if he can't resist her. It's only temporary. It has to be.

He's too old. And cynical. And he likes his bedroom games too dirty.

And, oh yeah, her brother will never forgive him.
