Hardwired (Hacker #1) by Meredith Wild
Determined to overcome a difficult past, Erica Hathaway learns early on to make it on her own. Days after her college graduation, she finds herself face to face with a panel of investors who will make or break her fledgling startup. The only thing she didn't prepare for was going weak in the knees over an arrogant and gorgeous investor who seems determined to derail her presentation. Billionaire and rumored hacker Blake Landon has already made his fortune in software, and he's used to getting what he wants. Captivated by Erica's drive and unassuming beauty, he's wanted nothing more than to possess her since she stepped into his boardroom. Determined to win her over, he breaks down her defenses and fights for her trust, even if it means sacrificing a level of control he's grown accustomed to. But when Blake uncovers a dark secret from Erica's past, he threatens not just her trust, but the life she's fought so hard to create.
