Raina Prentiss never imagined that she would investigate a homicide beyond the comfort of her couch, armed with a remote, but that's exactly what happens when she inadvertently finds circumstantial evidence connecting her boss to not one, but two local murders. With the reluctant approval of her police lieutenant boyfriend, Danny, she launches Mission Bottle to obtain her boss' DNA.She recruits her co-worker, Tyler, to divert their boss' attention while Raina sneaks around and swipes his water bottle. But a simple waft of Tyler's scent, or the heat from his body, transports her back to the feeling of the feather-light pressure of his mouth on hers, teasing her, taunting her, during the passionate kiss she found herself entwined in a few weeks prior.With no DNA found at the crime scenes to match to their sample, Raina together with Tyler, and Danny and his detectives, continue to investigate. Because of her easy access to her boss, Raina is convinced that she is the key to obtaining proof and solving the case. Determination blinds the risks incurred by hunting a killer, as Raina uses inside information from Danny to plan her next mission. Having jeopardized her relationship, her job, a friendship, and maybe her life, Raina goes full force into the investigation without a badge, superpowers, or a vampire boyfriend.
