The Dragon Tyrant's Secret Heir

Leia was born with dragon blood. Her father gave her to a sea demon as a sacrifice, and she came out of it alive. Not long after, Prince Kalen was in the middle of a dragon blood crisis and she was the one who happened to save him. They spent a night together. The child she carried was born with blue eyes, and the birth took her dragon blood with it, so she had no powers left. For three years she stayed out of sight and raised the boy on her own. Kalen found her at the end of those three years and worked out that the son was the heir to the throne. He said he would keep her safe from the people hunting her. Some of those people are close to him.
