When God chooses Mary McDonald as His messenger, she's as surprised as anyone-perhaps more so than most. A seventy-three-year-old retired psychologist and recent widow, Mary has spent the past two years quietly grieving her husband's passing while struggling with the progressive deterioration of her eyesight. Her days now consist of carefully navigating her modest Tampa home, listening to audiobooks, and treasuring the occasional visits from her sixteen-year-old grandson, Jake. She's hardly the person anyone would expect to prevent World War III.

But as global tensions reach a breaking point-with nuclear powers posturing on multiple continents and diplomatic channels rapidly deteriorating-humanity unknowingly teeters on the precipice of its own destruction. It's in this moment of unprecedented crisis that Mary receives an extraordinary divine mission, delivered not through burning bushes or angelic visitations, but in the quiet sanctuary of her morning prayers. The message is both simple and staggering: she has been chosen to carry God's word to the highest levels of government, to speak truth that could save millions of lives.

Armed with nothing but her unwavering faith, a lifetime of wisdom earned through decades of counseling troubled souls, and the steadfast support of her tech-savvy teenage grandson who becomes her unlikely ally, Mary must somehow find a way to reach the president of the United States. The journey from her small Florida neighborhood to the corridors of power in Washington D.C. seems impossible-a elderly woman with failing vision attempting to convince the leader of the free world that she holds the divine key to averting global catastrophe.

As Mary encounters skepticism from family members, disbelief from government officials, and her own moments of crushing doubt, she must learn to trust not only in God's plan but in her own worthiness as His chosen vessel. Her grandson Jake, initially embarrassed by what he fears might be his grandmother's declining mental state, gradually becomes her fiercest advocate as he witnesses the undeniable authenticity of her calling. Together, they navigate a world of social media, security protocols, and political machinery that seems designed to silence voices like Mary's.

Yet as skepticism slowly gives way to belief-first in small circles, then in larger ones-Mary discovers that God's power to work through the most unexpected people is as strong as it has ever been throughout history. Her journey becomes not just about preventing a war, but about reminding a cynical world that divine intervention often comes packaged in the most humble of vessels.

In this gripping tale of faith, family, and divine intervention, debut author Susan Swanson crafts a story that is both intimately personal and globally significant. She reminds us that hope persists even in humanity's darkest hour, when the news cycles are filled with despair and the future seems uncertain. Through Mary's extraordinary journey, we're shown that when God has a plan, He can use anyone-even a legally blind grandmother from Florida who struggles to work her smartphone-to change the course of history.
