If you’re trying to query editors and agents and want an idea of what they want, you might want to get on Twitter. A group of editors and agents recently did a Query Fail day in which they share (high level) queries that didn’t work for them.
Agent Colleen Lindsay has more info on it on her blog, and you can follow the Twitter aggregate here. Some people didn’t like it, but in this business, it’s not about your feelings, it’s about the writing. Do what you need to do to get your story read. If some of these editors and agents are ones that you’re interested in, it would do you well to know what flips their switch.
