An unexpected pregnancy in middle age seemed like a blessing—until her in-laws made her life difficult and scheming outsiders plotted against her at every turn, making each day harder than the last.

He stands firmly by her side the whole way, tearing down her toxic relatives, slapping back the calculating villains, and clearing every crisis in their path.
