At these I fail. Horribly.
There's a reason the projects on the "My Writing" page here on the blog don't have blurbs or descriptions. And, yet, I do believe it's high time I remedied that.
I think the reason I fail is that I try to put too much information in. But then when I take out information people get lost. It's a delicate balance to handle, especially in fantasy. (Not to mention trying to not confuse the reader but also not give away a twist.)
I've been working and re-working my query for Lodestar over the last month or more. It's no closer to being something that would grab an agent than it was when I first wrote it out.
When I wrote a query for Oracles Promise as a means of boiling down my plot in preparation for revisions, it just depressed me because it seemed to highlight so many problems that felt impossible to fix.
I think that killed blurbs/one-paragraph descriptions for me. And possibly queries.
And don't even get me started on a synopsis.
