Stark Shadows by C.D. Bradley

The butterfly effect: The theory in which one small action, seemingly innocent, can set in motion an entire chain of events with catastrophic results.

When Kira Riley first collided with Owen Stark she never dreamed the path it would set her on. Separating herself from Stark she was determined to achieve her mission. No more distractions. But the wheels of fate have already begun to turn. Ghosts of the past have been awakened. Before meeting Kira, Owen Stark had been dead inside. He had forgotten how to live and love. He tried to fill the void with anything and everything until he was just numb.

From the first moment he crashed into Kira, the flesh and blood man knew there was no going back. She was the drug he must have. He knew he should have walked away. Now that he has crossed the line, he would stop at nothing to have her again. A relentless journey but one that has started the dominoes falling in a way they could have never predicted. Sometimes the danger in the shadows is the darkness of your own desire.
