Reviewed:
The author, as this review is written, has one third of all 21 stories on the site. It may be too soon to compare this story to all the other stories on the site, or other stories I have read in the Science Fiction genre. However, it is in interesting read and could be the basis for a suspenseful story as the basic idea is strong.
But, and there is always a but, as everyone has one, there isn't much suspense as the story is short and the ending isn't entirely a happy resolution of the problems of the characters. Not that I could write a better story, but Mr. Bywater has, and read some of his others if you doubt me.
I agree world peace, or whirled peas if you want a vegetable, is a desirable outcome of any conflict. It is not entirely clear to me that that is what you would get out of this zombie attack. The author sets it up that way and it seems logical as you read it, but upon reflection maybe it is just optimism. Or a quick way to resolve the story.
The plot is strong, much stronger than the characters. I will give it an eight, which is an A as I grade papers. I saw no problems with technical quality, so I will also give that an eight, another A. Its difficult to downgrade what otherwise is a nice effort, but I have read science fiction that appealed to me much more than this story. Perhaps it does not have much in the way of character development, romance or conflict resolution. Its not just that the difficult was accomplished quickly, the impossible was done just as fast. Often in the next paragraph or so after the problem was exposed. So I will use a six, which is a C, average, to rate this story's appeal to me.
I strongly recommend other, longer stories by this author.
