His To Protect by Kara Kelley

Alexis Riker is a liar.
Spinning me a sob story about finding her long lost father might have been enough to get my attention, but when it leads us into Colombia and into a mess with the ruthless Sanchez brothers, it might also be enough to get us killed.
But I’m the best private investigator in the business for a reason. I’ll get her out of danger. I’ll keep her safe… but in exchange, I want her in my bed.
She’ll call me Daddy.
I’ll call her mine.
