Zack's POV
The guilt has been eating him alive. When his wolf had thrust him back to his own mind, Zack was unguarded, completely mesmerized by his mate's beauty. Hence when the attack came, he was surprised. That small moment of weakness was enough for the lust driven wolf inside him. Somehow it seemed to have gotten stronger as it was crazed by its own instincts. Never had it ever acted out like this before. The only exception was the day that the wolf got angry at his actions and taken control only to go and mark his own mate.
