For some reason no one wants to write a blurb, feeling instead that cutting and pasting a 2-5 page synopsis is a better idea. I'm getting details about the writer's path to writing (I don't care that you started at 13 or how old you are now). I'm even getting details of the person's family life.
Queries are really very simple. Just as simple as a cover letter. I need you title, your genre, your word count and I need a brief 2-3 paragraph blurb about your book. Essentially the back cover copy for your book.
If you can't put that together I am going to immediately figure that you couldn't write the book either or are too lazy to do the many rounds of revisions you'll likely need prior to publication.
The only thing these poor queries do are irritate me and make it easier for me to empty out my inbox.
