Junior For The Mountain Man by K.C. Crowne

The marines prepared me for everything... Except for the most important job on the planet. A f*cked up world made me into the man I am today. Then Piper walked back into my life. She woke up the beast I had locked away. I need to have her. Own her. Taste her. But, men with a death wish want to harm her and Caleb. I'll protect them both... And finally show my little sister's best friend... What she's meant to me all these years.
