The board is set. The walls of Castle University, once my stronghold, now echo with the whispers of war. As the Queen, I've faced betrayal, navigated alliances, and survived attempts on my life. But nothing has prepared me for this. My Kings, my protectors, are the only certainty in a world of chaos as an unseen enemy casts a shadow over our hard-won peace. In the dark corridors of power, I tread a dangerous path. The whispers call me a monarch of manipulation, a mistress of the great game. But I am not just playing for power; I am fighting for our future. As secrets unravel and loyalties are tested, my heart and my crown are on the line. But they underestimate me. I've turned gambits into triumphs and faced down so-called kings without flinching. Now, I must lead us through the ultimate test, where the only way out is through, and the only ending I will accept is the one where my Kings and I emerge unbroken. For in this grand finale, it's not just a happily ever after at stake-it's a legacy that will echo through the ages. And I will claim it, whatever the cost. This is a dark academia reverse harem with plenty of TWs. This takes place in an entirely fictional world set in the UK. This is the third book of three in the Kings of Castle.
