Obsidian Threshold: Bondage, Surrender, and the Fire Between Fangs: A Gritty BDSM M/M Romance

by Ash Wilder

Detective Galen Holt knows control—until he’s assigned to surveil the city’s most exclusive BDSM club, where obedience is currency and trust is everything. Scarred, armored, haunted by the violence he polices, Galen is drawn to the club’s master, Silas Vernet—a Dom whose every command cracks Galen open in ways he can’t bear or resist. When the hunt for a violent predator pulls them together, duty and desire collide. Galen can’t decide if Silas is the answer to his deepest needs or a dangerous distraction from the darkness stalking the city’s underbelly.

Heat High—explicit M/M exchange of power, surrender, and slow-burn obsession. Hurt/comfort, consent, and the thrill of being truly seen.

This is where survival ends, and surrender begins.

Galen hunts for a BDSM abuser known as the Red Wolf with the help of Silas. Silas convinces Galen to experience a scene to gain an understanding of BDSM.

"What you're feeling now—this trust, this peace, this willingness to be vulnerable—that's what consensual submission looks like. It's about choice and safety and mutual respect."
"Real training. Deep submission. The kind of experience that will make you believable as a target while giving you the tools to survive when things go wrong." Silas's voice dropped to barely above a whisper. "I'm talking about breaking you down and building you back up, teaching you to find strength in surrender."
"The most important thing to understand," Silas said, circling him with predatory grace, "is that submission isn't about giving up. It's about giving over. You're not becoming weak—you're choosing to place your strength in someone else's hands."
When he was finally secured—arms bound behind his back, legs spread wide, body supported by the rope harness—Galen felt like he was floating, suspended between earth and sky in a space that existed only for the two of them.
"You found the place where pain becomes pleasure, where surrender becomes power, where losing yourself means finding something better."
"This level of submission, this depth of trust—it creates bonds that are almost impossible to break. Are you sure you're ready for that?"
They were Dom and sub, connected by bonds stronger than rope or law or logic.

Galen accompanies Eli to his dungeon and experiences an abusive scene.
Will he discover who is the Red Wolf?
