Seven flames mark seven years. When the seventh dies, eternity ends. When seven-year-old Lucy Harper falls through the artificial sky above Evanus without a heartbeat, she carries a warning burned into her arms: WHEN THE SEVENTH FLAME DIES, ETERNITY ENDS. Lucy vanished from Alabama seven years ago, yet she has not aged a day-and her impossible return announces the arrival of the White Rider. The first prophetic flame is already dying. Zephira, the Crownless Queen, has spent her life caught between Heaven and the hidden city beneath the human world. Now the bloodline Heaven tried to erase may be the key to stopping a conquest disguised as peace. At her side, Daniel Mercer struggles to understand the Mercy Light awakening inside him, a power capable of joining forces that should never touch. With the three-hearted hellhound Vharok and the rest of the Five, they follow a trail of missing children, stolen memories, resurrected soldiers, and doors that open into a city built from the dead. Above them, Adrian Calloway transforms the Unity Compact into a global promise: no borders, no war, and protection from the supernatural. But his White Crown feeds on surrender. Every government that accepts his authority strengthens the Rider behind him, and every promise of safety tightens another chain around both worlds. As the Seven Thrones fracture, ancient clans choose sides, and the Veil begins to collapse, Evanus is dragged toward the surface for all humanity to see. Zephira and Daniel must decide how much truth they are willing to reveal-and what they are willing to sacrifice-before the first flame goes dark and peace becomes the deadliest weapon of all.
