Loving the Secret Billionaire by Adriana Anders

Mystery man, recluse, finance guru… Virgin.
I was a shut-in for a reason. With too many secrets, too much to hide, and way too much at stake, I spent years in my mansion in the woods, never trusting a soul.
So, when a stranger showed up at my door, with her plans to save the world, I should have sent her away, like I’d always done.
But from the second she arrived, I couldn’t resist Veronica Cruz. She was all the things I’d been missing—passionate, generous, and so damned sexy.
I let her into my life, gave her everything—including my heart.
Now, the one thing she wants is the truth. The question is, will she still love me when she knows my secret?

Loving the Secret Billionaire is a sexy standalone novella in the Love at Last series, featuring a virgin hero and a slightly older woman.
