Dark Room is a novel with two-story lines, in my opinion. You have one where Mia is being stalked by her ex-boyfriend and Parker, being her brother's best friend steps up to be her "bodyguard". Then there is the other part where both characters go to a sex club, unbeknownst to each other. They both choose and get paired up to be partners in "the dark room", where no lights are found and anything goes.
I enjoyed the story, I felt like the Authors could have made the sex scenes a little naughtier. They could have gotten more into BDSM, but besides that...I enjoyed it very much!
