Hard to Know by Jason Collins

CADEN:

I’ll never forgive him, but I’m stuck in the car with him.
My sister needs me at her wedding, but I didn’t know I’d be hitching a ride across the country with Ben, my high-school nemesis. That’s too much time to spend with the last guy I want to see, but I don’t have any other options. We might not get along, but we’re adults now, and I won’t let my sister down.
Ben and I have history, and it’s not the kind of history I can forgive. But this new Ben isn’t the jerk I remember, and that makes it even harder to ignore how hot he’s gotten. It’s almost enough to make me forget what he did—almost.
He was a player back then, and for all I know, he’s probably gotten worse with age. He’s still my nemesis, and it’ll take more than those smoldering eyes to get me to trust him.
Old rivalries don’t burn out—they simmer.

BEN:

I’ve changed, but Caden’s grudge hasn’t.
When my cousin asks me to give a stranger a ride across the country, I figure a friend of his is a friend of mine. But when I recognize the handsome stranger as Caden, I realize I’m about to be trapped on a road trip with a guy who’s hated me since high school.
What happened between us is more complicated than he thinks, but he doesn’t know that. The damage was done a long time ago. Still, that doesn’t stop me from imagining what his body would feel like under mine. With him this close to me, it’s impossible not to wonder.
I don’t need a relationship, especially with the problems I’m facing at the youth center I run. But when it comes to trouble, Caden might be the only guy I can turn to—if this road trip doesn’t kill us.
My heart’s in the hands of my worst enemy.
