RAGE (The Rage Series Book 2) by MJ Riley

uptown penthouse.
                  It was a house, he reminded himself, that had been bought with Mathers money—which was about as filthy as it came in his opinion. The realization hardened him, and as he closed the door behind Charlotte, his embarrassment disappeared.
                  A feeling that still lingered, no matter how much he tried to dispel it, was the acute awareness of the queen sized bed that took up most of the space in the room. Now that he knew that Charlotte was his half-sister, David had tried numerous times to conjure up feelings of disgust when he remembered the intimacy they'd shared. The problem was that he simply couldn't. When he remembered Charlotte's sighs and coos of pleasure and the way she arched against him when he hit that sublime spot inside her, he still became painfully aroused.
                  Even now, he was struggling against the quickly awakening organ between his legs.
                  The woman across from him didn't appear to be unaffected either. She glanced at the bed several times before hesitantly settling on the very edge of it. It took a moment, but David finally followed suit, sitting at the extreme opposite end of the mattress.
    “Well?” he finally asked in a low voice. He couldn't think of a single reason for why the heir to the Mathers fortune would have come to visit him now. Wasn't she supposed to be planning a lawsuit of massive proportions against him?
                  For a moment, Charlotte said nothing. Then, with a shaking hand, she withdrew a thick manila folder full of papers from her bag. Placing it on the bed, she edged it towards him. When he glanced up at her in question, he was shocked to find her gaze completely unsure.
    “These…” she started slowly, before clearing her throat, “I found these on my father's private server in the manor in Long Island. I assume they're going to be in agreement with anything you might want to tell me about your family and why you did what you did.”
                  David's gaze became slightly disbelieving for a moment before he picked up the folder from the bed and opened it. A thick stack of pages met his gaze, all patents. However, unlike the patents he'd become used to working with over the past six months, these were not marked with the name Mathers Incorporated, but with that of his father, Lester Marscomb.
                  Or, at least the man he'd thought was his father.
                  No .
                  At the blasphemous thought, David hardened his resolved. Even in death, Lester was ten times the father that Emerson would ever be. The man was trying to have him put away for God's sake. He delighted in his torment! Though his father might have had problems, David knew that Lester Marscomb had loved him until the day he'd died. His love had been so overwhelming that he committed suicide.
                  He couldn't imagine Emerson Mathers ever taking his own life because of love for another human being. The man would be selfish until the day he died, without question.
                  As David flipped through the papers, he felt himself becoming more and more desolate. There were images of Emerson and his father together, working on a new schematic, dates of both hiring and termination, personal letters from Lester Marscomb practically begging Emerson to retract his blacklisting requests from all nearby companies. It was a paper trail of suffering. When David finally came to the nude pictures of his very young and gullible mother, he'd had enough. “So what?” He tossed the folder aside in disgust as he drew his hands over his face, his heart like a rock in his chest. “Now that you know what your father has done, I've become someone for you to pity?”
                  “No,” Charlotte replied quietly. She looked at her hands rather than face him. “That's not
