Grumpy Billionaire Mountain Man: Enemies to Lovers Romance by Kathilee Riley

STUCK FOR FIVE DAYS IN A MANSION OF THE BILLIONAIRE I HATE.
I’m about to make partner at my law firm. I just have one task ahead of me. Convince a recluse billionaire to sell his land.
Should be simple, right?
No.
Not when that billionaire is Adrian ‘Heartbreaker’ Parker.
The cold-hearted player who seduced me out my panties five years ago then shattered my heart into pieces.
