In a society where the soulless are condemned to lifelong servitude, 20-year-old Ellie has resigned herself to her fate as a servant on the Doolittle estate. Deemed incapable of love or emotion, Ellie suppresses her feelings and any hope for a future beyond the estate's walls. But everything changes when she uncovers a startling secret about her past-her mother's true identity-and learns of her own royal lineage as the last heir to the throne. Forced to flee after an armed invasion, Ellie embarks on a perilous journey to the palace, where she discovers the true extent of her family's dark history. The power of the Grail, an ancient relic capable of stealing and restoring souls, becomes central to her fight against a corrupt system that exploits the soulless for control and power. Alongside Harrison, an unlikely ally who helps her discover emotions she was taught she couldn't feel, Ellie navigates a country in turmoil, as the fate of countless lives rests on her shoulders. A girl who was raised feeling trapped in a system might just find that she has the power to bring the entire thing down.
