Soulmates AU: Songs in your head are your soulmate singing. For as long as she can remember, Emma Swan has heard a voice in her head. A man singing to her that no one else can hear. The voice comforts her through the years, but just who is he? Killian Jones never expected a soulmate. But then he hears a voice in his head. A voice that won't let him fall completely into revenge

The nights aboard the ship could be cold, and on their way to Neverland, the timeless land, Emma found out that the melody of the sea was too hard to resist. Rated M for a reason.
