When mortal and immortal meet at the boundary of land and water...
As a boy, Adam had a sensual encounter with the elemental spirit of his family's lake. Or did he dream it? Now, in middle age, he retreats to this refuge to reassess his life after a heart attack. Melia, the undine who dwells in the lake, eagerly welcomes Adam's return. Although the last thing she wants is to be ensnared by human emotions, she feels affection and desire for the young man she remembers.
But Adam plans to sell off most of the surrounding land to a developer. To save her home from ruin, Melia sets out to seduce Adam. In the process, though, she risks losing her heart and gaining what she never wanted—a human soul.
