He's my sister's ex, a stubborn jerk, and completely off-limits.

Getting a man to give up custody of a son he didn't know existed should have been easy. Trouble is, nothing with JP King is ever easy.

Suave, grumpy billionaires aren't supposed to have strong hands or filthy mouths, and I never expected our snippy banter to be so much fun.

JP regards me as something he scraped off the bottom of his dress shoe, but when this reluctant single dad looks at my nephew, there's a softness there he struggles to keep hidden.

He may be gruff and uptight, but something simmers beneath his controlled, polished exterior. Sure, I'm wild and reckless, but when we're forced together as guardians, everything changes.

His cold and calculated exterior melts into hushed conversations and lingering stares. The more we fight, the harder we fall.

I'm scatterbrained, unconventional, and everything he's been missing.

The closer we get, the less we understand why we were ever at odds.

. . . until just like that our lives are turned upside down.
