This was an interesting read. I liked the idea of the whole community in the forest and the forest being alive, but the forest didn't really seem alive in the story. The only time we got a sense of it was at the end, everything else was written like it was done by the dead soldiers using the forest.
The characters were interesting, but I felt they all had a certain monotony with some topics. Such as, May glossing over what trauma she went through that caused her to hate the movement/outsiders, even though she was an outsider herself. And then the flashback was only to show that she was part of the movement and them Grams gave her a chance to desert the movement. All we know from what we got was that the movement started a war with the forest. Which I am extremely confused about, because what would cause a group of people to go, "You know what? Fuck them forest dwellers and their forest!"
There were also some grammar and spelling errors through the story, but those can be fixed, so it's not much of an issue. Either way, good job!
