When eleven-year-old Reenie Kelly's mother passes away, she and her brothers are shipped off to live with their grandmother. Adjusting to life in her parents' Midwestern hometown isn't easy, but once Reenie takes up a paper route with her older brother Dare, she has something she can look forward to. As they introduce themselves to every home on their route, Reenie's stumped by just one--the house belonging to Mr. Marsworth, the town recluse. When he doesn't answer his doorbell, Reenie begins to leave him letters. Slowly, the two become pen pals, striking up the most unlikely of friendships.

Through their letters, Reenie tells of her older brother Billy, who might enlist to fight in the Vietnam War. Reenie is desperate to stop him, and when Mr. Marsworth hears this, he knows he can't stand idly by. As a staunch pacifist, Mr. Marsworth offers to help Reenie. Together, they concoct a plan to keep Billy home, though Reenie doesn't know Mr. Marsworth's dedication to her cause goes far beyond his antiwar beliefs.

In this heartwarming piece of historical fiction, critically acclaimed author Sheila O'Connor delivers a tale of devotion, sacrifice, and family.
