It's a beautiful sunny day at a secluded beach and a family is getting ready to enjoy their time at the beach. That seclusion is quickly destroyed by another invading family and a roaming Kabyle whose first impressions come off as a creeper. While they argue amongst themselves and each other, a dead body floats towards them; it's of a woman. After discovering that body, it's all downhill from there. More people start to come to the beach and discover there has been a murder. But after awhile they start realizing that it's not the body they should worry about but something else. There is something off about that beach and the mother of the first family recognizes it but only vaguely.
Jesus, how terrifying of a thought is that? Knowing that you're going to die on a beach with strangers, no one will find you and that your children are going to meet the same fate you will. That your children are not going to have full lives and that their mental state will stay the same when they get older and not experience the wisdom and beauty of old age.
I keep harkening mortality because it's something that hounds me everyday. I'm not one to believe in an afterlife and the idea of not existing anymore is terrifying. So I can, to an extent, understand what these characters are going through. Reading Sandcastle has had a lasting effect on me. It made me think about myself, of all the things I've accomplished and have not accomplished but plan to. And I like that. I like it when something forces me to think of a big issue like mortality and one's self.
