Enemies, cellmates, true mates—and a drug designed to destroy every wall between them.
Mackenzie signed up for a dangerous clinical trial out of desperation. Twelve weeks sealed in a remote facility with a stranger, no way out, and an experimental drug burning through her system.
Then her partner walked in. Alpha Ryken Storm—the wolf who cast her out of his pack as a child. The one man who knows she's a forbidden hybrid who was never supposed to survive.
He's crueler than she remembered. And the heat in his eyes has nothing to do with hatred.
But Ryken has a mission—one that could end with Mackenzie in a shallow grave. As the drug tears down every wall between them, the line between enemy and mate gets dangerously thin.
When claiming and killing look the same, who breaks first?
