Hi Beth!!
Excerpts for Water's Edge appeared in some editions of...Night Whispers, I think it was. But during the writing, JM said she actually decided what she was writing should be two separate books. So what emerged was Someone to Watch Over Me. You may notice that the car crash in the beginning is almost the same as the one in the Water's Edge excerpt.
So Water's Edge was never actually published, nor have I heard anything about JM having any future plans to go back to it! But maybe some day... After the new Westmoreland trilogy!
