Trench Queen

Evelyn, a low-born girl, enters an elite academy that hunts sea monsters. Falling into a sea cave during training, she meets Nerian, the imprisoned Blue-Gold King of the deep ocean. Ignoring prejudice, she secretly helps him, forming a spiritual bond. Headmaster Vance leads fleets to seize the sea king’s power. Evelyn unites sea clans and defeats his conspiracy with wisdom. She gains full coastal command, rules the ocean with loyal Nerian, ends the hatred between humans and sea creatures, and ushers in an era of peaceful coexistence.
