The Deep Sea Tyrant's Forsaken Mermaid Bride

Doris, the most scorned princess of the Mermaid Kingdom, has no magic and cannot bond with a spirit beast, leaving her an easy target for those who look down on her. After she discovers her sister in an affair with her own boyfriend, her father's assassins are sent after her. Fleeing with nowhere left to go, she dives into the Eternal Abyss, where she comes face to face with Merrick, the feared Abyssal King. The man before her is the same face that has haunted her dreams, and he may be the only one able to awaken the power sleeping inside her.
