Tank's Fortress. Steel Vengeance MC, #5

He built bridges. She analyzes why they fall. Together, they'll demolish the conspiracy that turns construction into murder. When structural engineer Dr. Amanda Ford discovers that building collapses across Detroit aren't accidents but systematic sabotage, she becomes a target for the criminal conspiracy profiting from defective materials. Her investigation threatens billions in illegal profits-and that makes her expendable.
Eric "Tank" Price built his reputation on one principle: protect what matters, destroy what threatens. The Steel Vengeance demolitions expert has spent three years hunting the criminals who murdered his construction crew through sabotaged materials. But the brilliant woman with fire in her eyes and evidence in her hands is making him want something he thought was impossible-a partner worth protecting forever.
Amanda came to Steel Vengeance for protection from assassination attempts. But the dangerous ex-engineer with deadly skills and gentle touch is making her question everything she believes about justice, violence, and love. When their investigation reveals that construction sabotage reaches federal levels of corruption, Amanda and Tank must choose between legal solutions that enable more murders and systematic elimination of threats through lethal force.
Because the criminal conspiracy hunting them has already killed forty-three construction workers, and only an alliance between engineering precision and controlled violence can stop the killing. Some structures are built to last. Some justice requires demolition. Some love conquers even systematic murder.
