A Billion Reasons by Jessa York

Nick
When my oldest rival makes a power play that endangers the love of my life—I know he must be stopped at all costs.
First I need to put back the pieces of everything he broke.
Including me.
After that?
He’s fair game.
But my sworn enemy isn’t the only thing that shows up to test my resolve.
That arrives in the form of a curvy, blonde temptress on my doorstep.
She’s got enough curves to stop any man dead in his tracks.
Including me.
