Hacking Mr. CEO by Anna Hackett

To save the only mother I’ve ever known, all I have to do is hack a tech billionaire.

My foster mother is sick. The woman who gave me a home, love, a life. I’ll do anything to find the money for her surgery, including using my skills as a hacker.
My name’s Remi, also known as Rogue Angel, and usually I work for a security company testing clients’ systems. But now a shadowy bad guy has tracked me down and given me an ultimatum.
I have to hack Rivera Tech—the biggest technology company in the world, owned by billionaire CEO, Maverick Rivera. If I do, I get paid and I can help my foster mother. If I don’t, my family is in danger.
Hacking Rivera is no walk in the park, and soon I find myself in a tantalizing game of cat and mouse with big, grumpy, and way-too-sexy Maverick. What I never, ever expected was for him to make me feel safe, or to threaten my closely-guarded heart, or to ignite every single part of me.
I can’t drag him into my mess.
But Maverick has other ideas, and he isn’t a man who takes no for an answer.
Each book in the Billionaire Heists Trilogy can be read as a stand-alone, action-packed romance.
