Feyre returns to the Spring Court — not as a loyal subject, but as a spy. Determined to uncover Tamlin’s role in the looming invasion and gather intelligence on the ruthless king threatening to tear Prythian apart, she must play a dangerous game of deception where one wrong move could cost her everything and everyone she loves. As a full-scale war descends upon the faerie lands, Feyre and Rhysand must navigate shifting alliances among the cunning High Lords, seeking unexpected allies before it is too late. With the fate of both the mortal and faerie worlds hanging in the balance, the time for choosing sides — and making sacrifices — has finally come.
