Lena's dreams of a happily ever after are shattered when she realizes she ran off and married the wrong man. After a painful divorce, she returns to her childhood home in Montana, back to her parents. But when they learn she's with child, her parents send her away to the home of a family friend in Washington State until the baby can be adopted. There, she meets Sullivan, a widower who brings his physically handicapped daughter to the physician Lena is living with. Although she’s not looking for romance given her condition, Lena finds herself drawn to Sullivan and his kind heart, grateful for a friend. But when the plans for adoption fall through and the stock market crash plunges the country into a financial panic, Lena's plans to return home to Montana are upended. She must decide if she is ready to become a single mother at the onset of the Great Depression or if she can trust her child to the care of another family. Set against the backdrop of one the United States’ most challenging historical periods, A Plight of Mercy offers a heartwarming tale of love, resilience, and parental sacrifice.
