The story is above my intellect. :/ Our MC loves swimming and the ocean. She plans to be one of the handful of women to swim across the English channel. Since she was about 4 she has occasionally seen a woman in the water who has given her, her first kiss, some air or strength (or something) at other times. As a teen, the woman in the water has shown signs of jealousy when the MC has brought a gf there. She comes to believe the woman in the water is haunting her or is maybe her own fear. She finally gives into this other self or her own fear and the story ends. ( )
