Van is a merman who has lost everything: his voice, his family, and his place in the world. Forced to work as a slave in a mansion located in a town by the sea, he dreams only of one day returning to the water. His life changes when he meets Jens, the sole inhabitant of the cursed island of Fiska. Unlike any human Van has encountered before, Jens is kind and gentle. As the two grow closer, Jens becomes determined to buy Van’s freedom and bring him to his island home. But there is a strange condition for Van’s liberation: before he can be freed, he and Jens must fall in love. The story unfolds in this seaside town and on the mysterious island of Fiska, following the developing romance between the enslaved merman and the lonely young man who holds the key to his salvation. Major narrative arcs include Jens’s efforts to purchase Van from servitude, the pair’s growing emotional bond, and the central challenge that their love is not merely a desire but a requirement for Van to ever see the sea again.
