Sold into servitude at the age of eight, Chloe was molded into a top-tier covert operative for the Kingdom of Hagl, mastering unparalleled disguise skills and martial arts. After more than a decade of carrying out dangerous missions, she makes a devastating discovery: her handler and boss, Lancome, concealed the death of her family in a fire to prevent it from interfering with her work. Feeling utterly betrayed, Chloe fakes her own death during a mission and flees to the neighboring Kingdom of Ashberry, assuming the identity of a missing woman named Victoria Sellers to pursue the only thing she has ever wanted: a normal, peaceful life.

Upon arriving in Ashberry, Victoria’s plans for a quiet existence are immediately complicated when she takes in an abandoned six-year-old girl named Nonna, becoming an instant mother. Her retired spy skills, however, prove difficult to suppress. She inadvertently captures the attention of the capital’s knight captain, Jeffrey Asher, by assisting him in arresting a thief. As she takes on various jobs to support her new family, her extraordinary talents in combat, deduction, and disguise continue to surface, drawing the admiration of her neighbors and the romantic interest of Jeffrey, but also the suspicious gaze of figures like the kingdom’s second prince.

The first narrative arc follows Victoria’s struggle to balance her desire for a low-profile civilian life with her ingrained habits of a spy. As she builds a found family with the adoring Nonna and grows closer to Jeffrey, her former employer from Hagl begins to suspect she is still alive. Shadows close in on her new world, forcing her to use the very skills she swore to abandon in order to protect the life she has built. She eventually succeeds in evading her immediate pursuers and finds happiness, culminating in her marriage to Jeffrey.

Five years later, the family returns to Ashberry after an extended stay in the distant land of Shen, where Nonna mastered a unique martial art. Now twelve years old, Nonna is a remarkably capable and tomboyish fighter. Victoria, now more settled into her role as a mother and wife, discovers a hidden cipher inside an old romance novel, leading to a treasure hunt that reveals long-buried secrets of the Ashberry kingdom. This adventure forces Victoria to confront how much she has changed, as she struggles between her past identity as a lethal operative and her present life as a mother concerned with etiquette and domesticity.

In the subsequent arc, the political situation grows dire when the discovery of a gold mine on a neighboring border incites threats of war. When the wife of Prince Carlos survives multiple assassination attempts and her body double is injured, Victoria is strong-armed by the crown into serving as a temporary decoy to uncover the plot against the princess. Simultaneously, Jeffrey is sent to the border for peace negotiations, leaving Nonna to her own devices. Demonstrating her growth, Nonna becomes an agent of chaos, inadvertently curing her grandmother’s frailties through physical therapy and parkouring through a riot. As Victoria succeeds too well in her mission, bonding with the princess, both she and Jeffrey find themselves forcibly re-enlisted into the service of the crown, realizing that escaping a life of espionage is far more difficult than they ever imagined.
