Very pretty. The title fits it very well, as it sounds like the owner of voice to the song was shipwrecked, and it sounds like it's calling for help. Lamenting for past mistakes, remembering everyone and everything they love.
My only problem is that I feel as if the song takes a little too long to build up to the really emotional stuff. But that really could just be my ADD talking, so take it with a very small grain of salt.
