Wild Obsidian: Ritual. Wild Obsidian, #4

This book, and entire series, are for those who want a little bit of...bite in their romance. Who want the emotions to dig in and draw out your own healing... Enjoy After twenty years in the Army, Grant Rooker knows how to follow orders-but not how to live without them. Retired, restless, and sinking into silence, he's a man built for structure in a world that no longer demands it. Enter Dr. Casey Hale-pediatric trauma surgeon by day, Domme by choice.
She sees what Grant can't: the anxious discipline hiding behind his control. When she offers him mentorship inside Obsidian, the local BDSM club, Grant expects pain and punishment. What he finds is something far more dangerous-peace. Through simple tasks, quiet rituals, and a connection he never saw coming, Grant begins to rediscover purpose. But surrendering to Casey isn't about losing power; it's about learning how to trust, to serve, and to heal.
When high-protocol night arrives, every lesson, every breath, and every boundary will be tested. Because sometimes the bravest thing a soldier can do is kneel. Welcome to Wild Obsidian, where consent is Queen
