What if you opened your email one day and you got a really badly-written query letter? And what if the first paragraph of that query letter was composed entirely of annoying rhetorical questions? And what if those annoying rhetorical questions never actually told you anything about the plot of the proposed novel? And finally, what if, after opening this email, your head actually exploded?
Okay, pay attention: See that paragraph above? See how annoying it is? Don't ever do that in the opening of your query letters.
That is all.
