Knight by K.D. Robichaux

Clarice
He’s been my best friend for eleven years, ever since I witnessed his heroism in Afghanistan and nursed him back to health. The young soldier grew into a man I could spend the rest of my life with. But I can never let him know just how much I love him, because not even a hero who lived through a war can survive my past.

Brian
She knows every little detail about me. There’s no one in this world I love and care for more. After years of meeting up on my mercenary missions to spend time together, she’s finally coming to see my home, my club, and meeting my friends, who don’t even know she exists. Will I finally be able to convince my secret lover to tear down her fortress so we can become so much more than best friends?
