This is great.
here is some questions:
1) Does the last name hubbard have any historical(is that the right term?) relevance?
2) What happens with Australia? does it play a major part in the war?
3) What colloquial language is used in the future?
4) What exactly happens to the water? does it get poisoned from radiation?
5) Have you actually met your parents? if so, what are their thoughts on you?
6) Does time have ends?
7) Lets just say that people from the future are manipulating events now, such as preventing a tragedy, making it never occur. If it never occured, no body would be sent back to stop it, which would mean that the event does take place. This would lead to the prevention of it happening again, and so on. What would happen in one of these situations?
