I'm in the process of submitting to agents and really confused about all the conflicting information out there about the covering letter. Some sites say it should be fairly lengthy, a pitch with a good hook, describing the novel in one or two paragraphs and going into some detail, some say it should be merely a few lines with little detail. Does anyone have any advice on this? I think I might be overthinking it, but do want to give my best.
I think I've got a good tight synopsis now, so I just want to get this letter as good as it can be before I hit send :)
