Claire has always been the responsible one until she allowed herself one wild night. Claire had always been in control, but after dealing with her troublesome sister's drama, she allowed herself to loosen up one night. Especially because the handsome, muscular, and intelligent stranger she met at the bar was just too perfect to resist. The way he ignited every inch of her being that night was something she would never forget. Claire wasn't planning to see him again, until two pink lines showed up on her pregnancy test, and she realized she had no way to find her mysterious lover. Three years later, Claire's life was thrown into turmoil again when her sister went missing. When she turned to Griffin Security for help, the last thing she expected to see was an all-too-familiar face at their office - the man who fathered her daughter, Jace. Jace had never been interested in relationships until he met a beautiful stranger at a bar and thought she might just be the one to change that. But she bolted from his bed the next morning. Years later, she suddenly shows up in his office, even more stunning than he remembered. Jace can't deny the obvious. He still wants her, and this time he won't let her run away. Or will he? As they work together to find Claire's sister, the old chemistry between them returns with a vengeance. Nonetheless, Jace notices that something is different about Claire. Is it because she's worried about her missing sister, or is she keeping something from him? Once Jace uncovers the truth, will they still get a second chance at happiness? Or will Claire's secret keep them apart for good? The Unknown Child is the third book in the "Griffin Security & Protection” romance series. Each book in the series is a standalone with a guaranteed happily ever after for the couple, though it is recommended to read them in order for maximum enjoyment.
