1. "Having finished my novel, I'm now seeking representation". Having read your first sentence I am now saying no.
2. "Fighting her personal demons" "getting past her personal demons"
Unless you are writing SFF I don't want to hear about demons unless it's demon rum and you're offering me a swig.
3. "Reality TV attracts big audience numbers and this novel taps into that audience". This is a novel. Not TV. The only thing that assures audience crossover is a book ABOUT a specific TV show (Buffy being the primo example of that now). Just cause your book is about reality TV doesn't mean people who watch reality tv will buy it. The fact you think this is so, or that perhaps you know it isn't but hope I think it is, means one of us is an idiot. Let's vote. You win.
4. The utter nitwit who taped shut the pull tabs on the PRIORITY MAIL plus Delivery Confirmation envelope (total cost $4.55 plus SASE thankfully only at 39cents) such that when I cut it open with scissors I sliced his SASE beyond repair AND sliced his query. This over taping thing is beyond stupid. Priority mail querying is stupid too but if you want to enrich the post office that's your problem, not mine.
5. Dear "Mr." Snark.
6. "Knights of Templar/secret codes/hidden messages." Last year's news bucko. If this is what you're writing, you better try harder to make it sound fresh and interesting, cause "just like Dan Brown only better!" isn't as tempting as you think it is.
Tally: 15 queries, 6 so annoying that I don't want to read them. Actually, a pretty good day here at Snark Central.
