For fans of Chloe Gong comes a slow-burn, enemies-to-lovers romantasy in which a young Shanghai woman must work with her ex, the London prince, to save their rival courts--if she doesn't kill him or fall back in love with him first.

It's been nine years since the accords were established and centuries of war between the Midnight and Dawn Courts settled into a cold peace. But when poison created to eliminate the Dawn Court royal bloodline is stolen, all signs point to the Midnight Court and that tentative peace threatens to break. To prevent war, the Emperor tasks Anna Liang, daughter of the Midnight Court's deputy, with working with Paris, the youngest prince of the Dawn Court, to find out who was responsible and prove Shanghai's innocence.

But underneath it, the real assignment: infiltrate the Dawn Court's school for espionage, win Paris's trust, gain intel, and then kill him--Paris, her first love and heartbreak.

Despite this complication, Anna is determined to complete her mission. But as her bond with Paris deepens and the true culprit is revealed, Anna must decide what she's willing to sacrifice to fulfill her duty, and if she even wants to.
