Insurmountable: A Dark Enemies to Lovers Novella

By Skye Callahan

A dark captive romance novella featuring a trafficking survivor, a morally compromised protector, master-and-slave dynamics and forbidden attachment inside the Retreat.

She has survived eight years as a captive. The man who claims her may be the first determined to keep her alive.

I was sixteen when they stole my freedom. Eight years later, I'm transferred to the Retreat, a hidden playground where wealthy men pay for women like me. When a patron leaves me beaten, the head of security takes me to his private rooms and claims me as his own.

Miles calls me his Little Dove. He gives me clothes, a door I can unlock and protection no captive here receives. But he was raised inside this organisation, and every kindness comes from a man who still enforces its rules.

As his attachment to me draws the attention of the Retreat's ruthless leader, protecting me begins to threaten Miles's position. I know better than to trust a master, but he may be the only man willing to change the world that owns us both.

He cannot give me freedom, but he may be the reason I survive long enough to reclaim it.

Insurmountable is a prequel novella to the Sins of Ashville series and reveals what happened inside the Retreat before Irrevocable. It can be read before Book One or later in the series. Perfect for readers who love morally grey protectors, captive heroines, forbidden relationships and intense dark romance.
