Well, what a wonderful excuse to be self indulgent! Let's talk about what will earn my vote, and what I will reject.
~Next, I love quirky characters. Stubborn kids, super geeky kids, kids that can talk to insects. I love it when the characters are insects, animals, monsters. Show me something from a different side of the situation---show me what it's like to be the ghost that haunts a house rather than the person who is being haunted. Tell me about the flea that just really likes biting dogs, the smellier the dog the better. That kind of thing.
~I enjoy humour in the language. Spooky books that are too serious do nothing for me. I enjoy "voice" like Elizabeth Cody Kimmell's in Paranorman, like that in Tim Burton's Frankenweenie. This point relates directly to point two above; if you create a unique character, that character will have a unique way of saying and seeing things. Stay true to your character's weirdness. That's all I ask.
~I personally don't like stories about royal or really wealthy characters that just remain royal or really wealthy. If we're going to have characters like this, either the character needs to legitimately earn the place of privilege, or she needs to lose everything. What I prefer even less is when the "normal" character discovers that she is actually the missing heir to a throne. I dislike the current trend toward hidden princesses.
~Too much kissing. Yuck.
~The whole "love at first sight" thing where one character loves the other---especially if that character would be out of the other's typical "league"---right from the start for no apparent reason. I have a hard time liking a character that seems so shallow.
Please note: all of the above preferences are not set in stone, so to speak. If your manuscript is about a sixteen-year-old girl that has been surviving in London's ghastly undercarriage only to one day discover that she is the illegitimate first born of Prince Charles' (she will discover a uniquely shaped birthmark, or maybe an unexplained scar that says in Pig Latin, "Incess-Pay"), and then one day she decides to confront her father and claim her rightful place, if it's really well written (like, really, really well written) I will be fine with it. But if she can also talk to mosquitos, that might be better. Just sayin'.
Please don't have anyone beat up her pet dog though. Seriously.
