The Warrior River Channing is every inch the hero—an ex-Special Forces operative with a body honed for danger and eyes that burn through Kat's every defense. His presence is intoxicating, a heady mix of confidence and raw magnetism that makes her pulse race and her thoughts spiral. But River is more than just a warrior; he’s a man with his own demons that haunt him. The Enigma Kat McDonald, the Golden Team’s enigmatic assistant, is a woman River can’t seem to resist, no matter how many rules he’s made to prevent this exact situation. She’s a tantalizing mystery, her every look, every whispered word pulling him in deeper. She’s off-limits, married…or so he thinks. She’s a woman with secrets, haunted by a past that she can’t shake. The Challenge Now, the lines between duty and desire are blurring, and as dangers close in, River’s prepared to risk everything to keep her safe. This isn’t just attraction…it’s survival. And for Kat, he’ll break any rule.
