I just recently wrote a story (it took me a week of an hour here or there) that a lot of my friends (im 15) love. It is a 30,412 word 128 paged romance-mystery-thriller for young adults/teens.
saying that the average book has 250 words in it... that means it would be about 122 pages... is that long enough? and it hasn't been edited by anyone really yet?

extra question: how does the editing process go? or how should it go?
