Nanko

She didn't fit into their traditions. He didn't care about her protests. In a world governed by ancient bonds, some connections are impossible to fight. River knew how to handle a crisis, but navigating a reality-shattering cosmic transition was definitely not on her horizon. Stranded in a breathtaking, high-stakes new universe, her survival instincts tell her to keep her distance, map out the terrain, and protect her freedom above all else.
Too bad the commanding alien warrior assigned to her sector makes it completely impossible to walk away. Nanko is an elite professional built for dominant rule and raised on the strict discipline of his brotherhood. He certainly didn't anticipate a fierce human female who matches his authority word for word and brings a beautiful, unpredictable chaos into his structured life. But the second his deepest instincts claim River as his own, his mission shifts entirely from keeping the peace to winning her complete devotion.
