Hi Silk!
Ok, so it only took me over two months to review this one, but I'm finally here. Let the party begin!
So first off, I'll be honest: This was hard for me to get into. I wasn't captured by it, nor did I become "lost" in the story. I actually found myself easily distracted as I read this, and forced myself to stop and start over so I could keep track of the story.
That said, there were some good things.
Specifically, I enjoyed your overall gritty, down to earth prose. While it didn't "Wow" me anywhere, and the sentence fragments you used weren't necessarily working, you invoked a strong mood. You also had some interesting characters, particularly when they reflected on what was truly difficult about war: the waiting, the writing to loved ones... anything but the fighting. That's great insight.
One of the first things I was confused about was your genre. I had no idea if this was sci-fi or fantasy or something else. Or, more specifically, I didn't know if this was a medieval setting, an alien setting, or a modern-day setting. Literally everything you mentioned could be present in all those times: canvas, uniforms, vegetables, metal weapons, soldiers, etc. You mention metal in a way that implies swords, but I never got a clear read on it. Truth be told, I never figured it out in the end. My guess is that it's a bit of sci-fi.
I don't need to know the specifics of the actual conflicts. I enjoyed that you kept this small and we stayed with the soldiers. But I really wish I knew what your world looked like.
I mentioned that the pacing was slow IMO. One thing that may have contributed to that was that your characters think and talk about a lot of "slow things". When your character is frustrated by waiting around, or being out of the loop, your audience can't help but think it too. In screenwriting, I've learned the hard way to not put lines like "I'm confused" or "I'm bored" in there because it just sets the audience up for thinking that as well.
The other contributor to the slow pace, I think, came from a lack of conflict. Yes, I know there were some battles and ambushes, but I couldn't really think of something that was challenging the protagonists in any way.
They had difficulties, but no hard choices to make. That may be the core of what's lacking here. I think I'll bold that for reference. ;-)
“What d’you think’s going on, anyway?”
That was on page 7. And I wasn't able to answer. I felt overwhelmed by half-details, and not enough exposition. I wish I knew what was going on. So far, not much has happened beyond some introspection and a vague news report that the valley was "taken" (off camera though)
The need to pretend is over, so they fight in soldier blue under a blazing sun
The section of text which starts with this sentence felt really weak to me. The sudden jump in POV didn't work for me. I think I know what you were going for here (a cold, emotionless, fly-on-the-wall feel), but it just wasn't working for me. Ditto for the other sections with this similar POV. If you would like to use this POV, consider using it as an opportunity to show us physical details of the characters. You can still convey emotions by describing their look, their posture, their breathing, etc.
Seryl snorted. Tiresome was one word for it.
Well done with mentioning Seryl very early on, and then actually showing him on page 4. You planted that well. Although when you first mention him in Darin's POV, I got the impression that Seryl was dead, not just retired.
The last few pages fizzled out for me. Again, I think I get what you were going for with the letter. But it didn't resonate with me. Probably because I had very little emotional connection with Darin. I respected them, and their efforts. But ultimately, there was nothing at stake. See my bold comment above.
You're a good writer, and I honestly see some potential in this story. You have a beginning, middle, and end. It just needs conflict to drive it home. I would love to read a revised version if you come back to this.
Good luck!
