Dr. Wren Harrison has devoted her life to one thing: protecting North Carolina's endangered Red Wolves. When a pregnant female goes missing, Wren will do whatever it takes to keep her - and her unborn pups - safe.Even if it means clashing with Cyrus Langston.A commanding prescribed burn specialist with a dangerous intensity, Langston plans to light a controlled fire directly across the wolf's path. The burn could be catastrophic, and Wren refuses to let a man with predatory eyes and an unsettling pull threaten her wolves.But the more time Wren spends with him, the harder it is to ignore the truth coiling beneath her skin. Cyrus doesn't just understand wolves - he is one. His presence is all heat and dominance, his interest sharpened by instinct he's never had to fight before. Every look lingers. Every touch feels deliberate. And once he starts circling her, neither of them can seem to step back.Cyrus Langston isn't the enemy she expected.He's a wolf - and for the first time in his life, his body is responding to a claim he can't anticipate, can't control, and can't pull away from.Once instinct takes hold, there's no pulling free.
