My opinion to Chapter 7.
First. I just wanted to say that this is a fantastic concept good job author! The plot from what I've read so far is solid.
Read the story now
Now for the criticism. One thing that the author need to do is add more descriptive sentences. I think it would really create a better picture in the reader's head as they're reading and make the story easier to follow. Another point I want to make is the abundance of grammatical errors and run-on sentences made the story hard to follow. Don't be afraid to put periods and split sentences up.
For the character's I don't know how to feel about them. Oliva isn't very likeable in my opinion, but that's just my take on it. Samuel is interesting and is probably my favorite character so far. I don't even know what the mom's problem is, is there context on why she is nasty acting later in the story? A plot and a wonderful concept is really important but characters make the story. If a reader has no attachment to the character there is no point in continuing the story.
Overall, this story has a superb concept but can improve on many things. I might read some more later.
