If I've written a YA novel over 100,000 words, will agents/publishers reject it right out simply because of word length before even reading my query? Or if my query is only so-so (which it probably is), could the word count tip the scales for tossing it?Don't be silly. The Amulet of Samarkand? The Hunger Games? These ring any bells?
...Unless by "over 100,000 words" you mean "200,000 words". If you're going to get into Deathly Hallows / Breaking Dawn territory, you better be J K Rowling or Stephenie Meyer, and I think I would have noticed that in your email address.
