Billy and Mongo

One castle. Ten Masters. And a secret that could burn it all down.

A tale of brazen desire, buried demons, and the fight for forever.

Mira Garcia didn't pull punches and didn't fear sassing a Dom. She'd waited years for the perfect fit. The moment Masters Cougar and Crow walked into Castle Sin, she locked her sights on the powerhouse duo with zero intention of playing coy.

They were her forever.
They'd better keep up.

Billy and Mongo had walked a long, brutal road together—one finally leading to peace at Castle Sin. Then they found her. A silver-haired vixen with a smart mouth and zero fear. The brat to their beasts. The match they hadn't dared believe existed.

But across continents, the demons from their past were stirring. Instead of running, the duo ran toward the threat—annihilation their only goal.

In the path of destruction came revelations that raised the stakes higher than they'd imagined.

Would the trio survive long enough to claim their forever?
