She confronts Kaelen, leader of the Silver Scale merfolk, with a USB drive holding his hidden secrets, forcing him into a one-year contract marriage by threatening to expose his non-human identity. Their first stormy confrontation reveals Kaelen’s silvery fish scales. Though wary of her leverage, he hides a secret: he collaborated with her father three years prior. Pretending to be spouses, they outmaneuver power-hungry clansman Damian. Through traps and trials, they uncover smuggling and murder plots, awaken their fated tide bond, defeat the traitor, and find mutual redemption amid the tides.
