I use to write ONLY in first person, past tense...It was just what came natural to me. I write a series for a website and for the past three seasons, it's been told in first person, past.
But now that I'm in season four as my characters reach their Senior Year of high school, I've switched to present tense. It just seemed natural to me as the whole of the fourth season is about the future and the fear it brings. The characters are constantly wondering, "What's next?"
That's why I feel present tense works...It allows characters to have true uncertainty. To be fair, even when I wrote in first person, past, I liked to think that my characters weren't actually telling "from the future", I didn't imagine them sitting in an arm chair, telling their grandkids a tale. I tried to keep it very ambiguous. I never like when a first person, past tense narrator mentions I'd later learn." or "Years later I'd come to realize..." it takes me out of the story. I want to always be kept in the "now" of the narrative(I include flashbacks in this)...
I think it's tricky and I think if the story is good, most readers don't take into account "Oh this is told in past tense, the narrator has to survive!" or even realize "Wait, this is in present tense".
So it leaves with some question..
I can't decide if I should write some story ideas I have in past or present tense because of this whole paranoia I have about whether it takes the viewers out of the "NOW"...
How do people feel about killing off a character in past? Can you kill off a PoV character in 1st person, past tense? I'll have multiple PoVs, so it isn't like I can't kill them off through another PoV, but would that work? And would audiences feel the danger?
And is it okay to have characters narrator in past tense but still not know the future? I'm not sure if this makes sense now that I wrote it but my other story is YA and will involve, "decisions about the future" and a death...so is it okay to have them, as narrators, not know this is going to happen. Basically it's as if they're telling the story at the end of the day or maybe even two minutes after it happened.
One idea I have was to tell the story in three PoVs in two tenses..PRESENT from the children, PAST from the mother..but then it became tricky when I decided I wanted the mother's PoV to at least be involved somewhat in the present(at least in concern to the death...)...
It's funny, I never use to think about past/present...but now I'm constantly debating it. And I think I'm sort of scared of past tense now since I haven't written in it in well over a year..plus the last THREE books I've read all happened to be(completely coincidence!) in present tense. It sort of scares me to go back to it haha...I'm worried I've forgotten how!
I guess since I'm only on my first drafts I'll write them in whichever way feels natural and see how it reads and take it from there...
And one thing I dislike, whether in past or present tense, is when we're getting a PoV from an average teenager and they sound like 30 year old English Professors. That takes me out of the story more than anything. The Knife of Never Letting Go is great with getting the voice right.
