Longtime Crush by Carrie Ann Ryan

When my best friend and I fell for the same guy in middle school, I stepped back.
I’d always expected to dance at their wedding.
Not sit in the back pew of her funeral.
I left town for my own reasons, but now that I’m back, it’s clear Sebastian Montgomery isn’t the same man I left.
He’s hard. Broken.
And a single father to an adorable little girl.
When it turns out he’s my new neighbor, I can’t stay away.
But I know I’m playing with fire and the heat between us burns enough to scorch.
I thought I was over my crush.
But now it might crush me.
