I'm currently in the midst of rewriting my WIP from past to present tense. (Yup, that's about as fun as it sounds.) I've never used present tense before--it hasn't come naturally to the story, the POV, or my writing style. But when I first scribbled down the first six pages of this story,* I used present tense. It was one of those Ouija board writing moments. Weird.
So weird, in fact, that I when I kept drafting the WIP I quickly switched to past. I wrote the whole first draft, all 65K, in past tense. Now that I'm finally revising it, I am switching the whole thing back. This is odd because I don't typically like present tense. I am rarely a fan as a reader, and definitely not as a writer. I worry that present tense is gimmicky (or will be interpreted as such). Mary Kole has some reassuring words on that; Philip Pullman does not.
The reason why I'm making this switch is that the narrator's voice came to me as present tense. The urgency works for the story; it complements the POV. Past projects would've sounded strange in present tense, but this WIP sounds strange in any other. And so I forge ahead, swapping was for is and cutting hads all over the place. We'll see how it turns out.
Do you favor one tense over another? Do you have strong reactions to reading any particular tense?
