Invariance - Prologue

Hey there. I like the title you've picked for the novel--it's pretty neat.

That said, I'm not a fan of prologues unless they're very-much necessary and very well-written, and I really don't think you need this one. It's very common to race through a couple of paragraphs, drop a character, state his importance, mention a few details that the reader is very likely to forget as soon as they enter the first chapter--and I'd suggest integrating all these details in the first chapter instead, where you can slow the pacing somewhat, and also establish more of a base for continuing the novel. Generally, prologues are more of a disconnect from the main course of the novel; they may introduce a situation that later acts as a tie-in to the rest of the plot, but that is usually nearing the end of the novel, or during the climax, or as a revelation. You've clearly introduced a main character here, whose story is to be continued throughout the rest of the novel, and because this ending acts as the basis for continuation, I'd label this as chapter one. A good example of a prologue is in Anthony Horowitz's Eagle Strike, where the characters introduced don't really tie in with the actual protagonist's story until the novel is almost at its end. (It's a brilliant book to check out, anyway!)

Moving on--it's kind of disconcerting for the war hero to die so early on in the novel--and I don't mean disconcerting in a good way. I'm pretty sure there'll be some sort of revival, that the hero won't really die, or maybe we'll be introduced to someone in the next chapter who can save him? As it is, I'm not intrigued enough to continue, A) because I haven't really grown to care for the narrator in the little time we've known him, and am unaffected by his death, and B) because there is little to spur me on. Where is the conflict--in the character's death? What exactly does this world consist of? A bit of rushed dialogue isn't enough to convince me to carry on; what this needs, short and simple, is a hook. It needs a sturdier base--a foundation, if you will. Focus on worldbuilding and character-development in the re-write, but let it be for now. I'm keen to see how you intend to continue this.

Keep writing! Keep up the good work!

This was a good work, but I found a few more errors. In the first three paragraphs, after people talked, you capitalized the next word, but it wasn't a name. For instance, ""Ten dollars for one gallon of milk?" The man said", should just be ""Ten dollars for one gallon of milk?" [t]he man said..."". Make sure that after quotation marks are put, the word that follows it is almost always uncapitalized, unless it is a name or a word like "I". Or, of course, unless you purposefully wanted to capitalize "The" for an unknown reason.

Now, like @Jumpyspot said, this does not sound like a prologue. It sounds more like part of the first chapter. This could work as a prologue depending on what the rest of the story will be like, but from what I know, it would function better as part of a chapter. If you want to make it a chapter, I would advise on making it a little longer.

Near the end, it got quite descritive and left me with an image in my head. I think you should work on using words to create images throughout your next work, rather than just at one point. Like maybe describe Kyle when the cashier recognizes him.

Otherwise, this seems like it has a good idea behind it. As your first time, this is good. Keep on writing; everyone starts somewhere!
