Hurricane August by Dakota Rebel

August –

Levi Morton is the biggest stick in the mud, boring, suit-clad jerk I’ve ever met in my life. When I was younger, I would do everything I could think of to torment him. To the point that I would have honestly said we hated each other. Except…I’ve never actually hated him.
I’m not sure how he roped me into pretending to be some corporate admin lackey, but here I am…and there he is. Suddenly, I want to torment him in completely different and less innocent ways.
Too bad he’ll always just think of me as the little brat whose presence he tolerates, and never bother to see the grown woman standing in front of him, wanting to be his.

Levi –

August Jones is a whirlwind of crystals, smudge sticks and nonsense. She’s been friends with my brother since they were kids and for years she was like the little sister I never wanted…until she became a grown woman and it was as if I’d never really seen her before.
We still fight like cats and dogs, she still drives me crazy, but now I can’t stop thinking about her. Dreaming about her. Wanting her.
This is supposed to be a business deal, but as much as I want to save my company, I’m starting to think that there is a lot more to gain from this situation.
