Let the SF wash over you and you will enjoy the moving, sad and funny story of a man searching for his father, lost in time. If however you enjoy mind-bending SF, you will love reflecting on concepts of time, memory and identity. And, if that's not enough, it's a page-turner as well!
I don't miss him any more. Most of the time, anyway. I want to. I wish I could but unfortunately, it's true: time does heal. It will do so whether you like it or not, and there's nothing anyone can do about it. If you're not careful, time will take away everything that ever hurt you, everything you have ever lost, and replace it with knowledge. Time is a machine: it will convert your pain into experience. Raw data will be compiled, will be translated into a more comprehensible language. The individual events of your life will be transmuted into another substance called memory and in the mechanism something will be lost and you will never be able to reverse it, you will never again have the original moment back in its uncategorized, preprocessed state. It will force you to move on and you will not have a choice in the matter.
