‘For a very long time, the days went by, each just like the day before, then I began to think, and everything changed’ Deep underground, thirty-nine women live imprisoned in a cage. Watched over by guards, the women have no memory of how they got there, no notion of time, and only vague recollection of their lives before. As the burn of electric light merges day into night and numberless years pass, a young girl - the fortieth prisoner - sits alone and outcast in the corner. Soon she will show herself to be the key to the others' escape and survival in the strange world that awaits them above ground.

Beyond the Martial Empire and within it, the threat of war looms ever larger. Helene Aquilla, the Blood Shrike, is desperate to protect her sister's life and the lives of everyone in the Empire. Yet danger lurks on all sides. Emperor Marcus, haunted by his past, grows increasingly unstable and violent, while Keris Veturia, the ruthless Commandant, capitalizes on the Emperor's volatility to grow her own power—regardless of the carnage she leaves in her path. Far to the east, Laia of Serra knows that the fate of the world lies not in the machinations of the Martial court, but in stopping the Nightbringer. During the hunt to bring him down, Laia faces unexpected threats from those she hoped would help her, and is drawn into a battle she never thought she'd have to fight. And in the land between the living and the dead, Elias Veturius has given up his freedom to serve as Soul Catcher. However, in doing so, he has vowed himself to an ancient power that demands his complete surrender—even if that means abandoning the woman he loves.

This is a world divided by blood—red or silver. The Reds are commoners, ruled by a Silver elite in possession of god-like superpowers. And to Mare Barrow, a seventeen-year-old Red girl from the poverty-stricken Stilts, it seems like nothing will ever change. That is until she finds herself working in the Silver Palace. Here, surrounded by the people she hates the most, Mare discovers that, despite her red blood, she possesses a deadly power of her own. One that threatens to destroy the balance of power. Fearful of Mare's potential, the Silvers hide her in plain view, declaring her a long-lost Silver princess, now engaged to a Silver prince. Despite knowing that one misstep would mean her death, Mare works silently to help the Red Guard, a militant resistance group, and bring down the Silver regime. But this is a world of betrayal and lies, and Mare has entered a dangerous dance—Reds against Silvers, prince against prince, and Mare against her own heart.
