Nerve gases (also known as nerve agents) are a class of chemical weapons. During Day 5, the terrorist group known as the Dawn Brigade (led by Vladimir Bierko) used a stolen nerve gas called Sentox to threaten America.
the number of words in a novel will vary depending on the genre a young adult novel will run between 20000 and 40000 words that would be the length of a novella in mainstream fiction many genres seem to have succumbed to supersizing a mass market western mystery or sf novel used to run to 60000 70000 words
Now, that's good advice. But I don't like to do things half-heartedly, so here is the bigger picture of length in fiction... A novel is anything over 50,000 words. A novella is between 20,000 and 50,000 words. A short story has a word count of under 20,000 words.
