And on this day we look at Charlie Jane Anders' (author of All The Birds in the Sky) #9 of her "10 Writing "Rules" We Wish More Science Fiction and Fantasy Authors Would Break"...
9) No present tense
The Green Giant.
(I kept Charlie Jane Anders' link for reference)
Mmh, a hard one for me to advice on. You are welcome to write in any tense you want, but if it is anything other than past tense you probably won't win me as a reader. As with First, I simply can't get into the story. Alas there are fans of First, so present tense might have some as well. The question is: How many and how many readers do you want and which tense tells your story best? Up to you!
