O.K., here's your first question (hopefully in a long line of them).
My story, Terrornet, is about a bunch of high school kids, and their crazy teacher who fight terrorists and other forms of evil with guns, and time travel. In the first book (of hopefully many), they are trapped on an island somewhere and forced to kill each other, kinda-hunger games like, except the kids (i don't have any names yet) figure that they don't need to kill each other, just outsmart the evil guy who controls the game. So they get to his giant castle, where some of them notice that they may all die. there is sex. teen preg as well (which would be the basis of the 2nd booK). they enter, and then most of them are killed, leaving the last boy to travel back and fix it, using a bit of Bill and ted type know-how (ex: the keys were there because they reminded themselves to go back after they fixed everything, and so they appeared by them reminding themselves to do it later). They get back to civilization, and then face the repercussions of their workings.
Is that YA? (and if so, what genre?)
