Hey Dollars. I am planning on writing a book about a rebellion that is the cause for a dystopia. The only problem is I do not know how I should start it exactly. If anybody could I ask please help me with this most annoying of challenges.

(sorry if this doesn't help- I don't know what a dystopia is...) I think it should start with some sort of action. Like a small attack on whatever the rebellion's against or a meeting of some sort. Something that has a high tension level or a small introduction to the area/reasons for fighting. I started mine with a main character running for shelter.
Main point: the first sentence has to be interesting

I thank you greatly for this information and hope that you may have a pleasant evening.
