Ariella Warlington, an intern at a psychiatric asylum in Boston, should never have opened that file. But her fate has been sealed ever since her mother, dying in childbirth, named her as the Little Mermaid. Her first patient? Kaelan Scott, aka "The Joker." A mute murderer with eyes as dark as graves, locked away for five years for killing 30 people. A monster. Yet, it is he who demands her. He who carved her name in blood on the walls of his cell. In the silence of the empty corridors, a bond as dangerous as it is irresistible begins to form. But getting close to chaos means risking getting burned. Ariella will discover that some love stories don't end with "happily ever after," but with sea foam, blood, and madness. Can she love the monster without becoming one of his own ?
