From Sanctum with Love (Masters and Mercenaries Series #10)

Psychologist Kai Ferguson has had his eye on Kori Williamson for a long time. His assistant is everything he's ever wanted in a partner-smart, caring, witty, and a bit of a masochist. More than a little, actually, but that's the problem. Kori won't admit her own desires. She's afraid of him and what he has to offer. Luckily for her, helping patients face their fears is one of his specialties.

Kori knows she wants Kai. Her boss is the most amazing man she's ever met. She's also smart enough to stay away from him. Having been down this road before, she knows it only leads to heartache. She's just found a place where she can belong. Another failed relationship is the last thing she needs. It's better to guard her heart and let Kai think she's frightened of his dark, dominant nature.

When Kai is recruited for an operation with McKay-Taggart, everything is turned upside down. Kai's brother, international superstar Jared Johns, is in town and Kai must juggle his family issues along with a desperate hunt for a serial killer. The investigation throws Kori and Kai together, and they quickly discover the chemistry between them is undeniable. But even if their newfound love can survive his secrets and her lies, it may not be enough to save them both from a killer's twisted obsession.
