Amber had long hoped Nelson was interested in her. Finding out that he’s a Dom convinces Amber to take a chance on her sexy co-worker. A matchmaker and a good friend, Nelson tried to resist his attraction to the gorgeous woman. He never expected her to hack his website. The innocent-looking woman was really a sassy sub who secretly wanted him. Both had struggled with finding matches in the BDSM lifestyle. While they are ultra-savvy in cyberspace, in real life things are much more complicated. Amber does her best, but Nelson’s past tests them both. She’s not giving up, and tests him right back. Nelson must rise to the challenge of the right woman who doesn’t walk away when things get tough.
