New release ‘Power of a Promise’ delivers high-stakes Christian suspense set in the Oklahoma Panhandle
A gripping tale of betrayal, spiritual warfare and the unshakable power of faith
ARDMORE, Okla. – When residents begin vanishing in the Oklahoma Panhandle, four undercover agents are sent to investigate. What they uncover is more than a criminal operation — it is a confrontation with darkness that cannot be defeated by human strength alone.
In her debut novel, “Power of a Promise: A Depiction of Courage and Conviction” (published by WestBow Press), Tina Tate blends tactical espionage with spiritual warfare in a suspense-driven story rooted in faith, redemption and the power of God’s promises.
Set in the fictional town of Lansbrook, the novel follows agents of the Worldwide Intelligence Network (WIN) as they pursue answers behind unexplained disappearances. As tension escalates, the team realizes they are not only tracking a threat — they may be targets themselves.
The four agents — Angela Porter, Kurian Imes, Jeana Westlund, and Vince Nash — each bring critical skills to the mission. Angela combines a background in criminal law with a strong spiritual foundation. Kurian, a natural leader trained in criminal justice, anchors the team under pressure. Jeana offers intelligence expertise and direct access to agency leadership, while Vince Nash provides technological mastery capable of neutralizing signals, cameras, and security systems. Together, they face not only external threats but internal battles of conviction, loyalty and faith.
What sets “Power of a Promise” apart from other suspense thrillers is its ultimate source of strength. The story does not rely solely on clever tactics, firepower, or human resolve. Instead, it reveals that true victory comes through the Word of God, faith in Jesus Christ, and unwavering spiritual conviction. When these forces confront evil, they prove mightier than any weapon.
“People are searching for hope, truth, and purpose in their lives today,” Tate said. “My story offers assurance that God is constant, faithful, and actively working even in the darkest times. I want them to feel the kind of hope that reassures them they are seen, loved, and never alone. If my story deepens their faith and brings souls to the redemptive power of Jesus Christ, then the book has done exactly what I meant it to do.”
