The Accountant

Elena is a beautiful, nerdy girl who loves numbers and rules and order. When she gets hired by a small investment bank she begins to notice problems with certain accounts. She also runs into the Security Director, a large, intimidating individual she becomes fascinated with. When she is threatened he drives her home, and there... things happen. Somehow, the astonished young woman finds herself in a darkly thrilling relationship with James Wild, a man ten years her senior.
Wild is a man with spectacular skills in bed, and no sense of the proprieties! Worse, he has a fascination for power and dominance games. Elena is more than slightly overwhelmed by the scalding heat that brings, and quickly finds herself on a thrill-ride she can't control. Meanwhile, someone is trying to thwart her investigation, and willing to get violent about it.
