Mr. Dirty (London Billionaire Book 3)

My life was great until my new neighbor made my life impossible. She can't stand me. And the feeling is mutual.
She's annoying, and persistent, and a pain. 

She's also gorgeous, and smart...and completely immune to me.

But now she needs my help with a little Ex payback and I'm more than happy to lend my expertise. 

Now all I have to do is keep from falling for her in the process. How hard can that be?
