I heard lots of people say getting an agent is easy, but finding a company to publish your work is hard. And judging by the writing about Erimentha's lesser known twin, there probably is a small chance that she will get a publishing deal. I think it would be a freaking miracle if she does get published.
Yeah, getting an agent is relatively easy, but few people manage anything beyond that. If you take a look at the authortube world, it's full of excited announcements that they've landed an agent, with no sold/published novel in the years after that.
Ruby's agent situation is also full of red flags. Some agents enjoy getting involved in the editorial process, but most generally only sign a prospective author when they have a book that's in as close to publishable quality as they can get it, because agents don't make a single penny from an author until they sell a book to a publisher.
Usually if an author submits a mess of a novel full of structural problems, plot issues and riddled with spelling, grammar, syntax and punctuation errors, the agent won't usually sign them even if they see promise there. If there's an absolutely killer premise there, maybe they'll sign it in rough shape because the hook is worth the time investment, but not for a generic, borderline-plagiarised YA book.
There's no sense in working for free for months just trying to help an author get a book to the point where they can finally start shopping a mediocre book around and getting rejections from publishers. And if they have to teach a writer the English language from the ground up, it's a lost cause. They'll usually tell the author to go away, hone their English skills, work on the book, iron out all the problems and resubmit when it's in better shape. They usually sign them when the book is at that point, not when it needs 7+ rounds of massive from-scratch rewrites.
Her agent also tellingly announced the book to prospective publishing industry buyers as "the debut of studytuber influencer Ruby Granger" which isn't true, but also tips their hand - they clearly only signed Ruby for whatever influencer cred she has. I highly doubt any agent would've touched this project in this state from any other writer who didn't have a YouTube fanbase. But just because an agent sees that as an easy sell, doesn't mean a publisher will. They'll have immediate access to the sales metrics that show just how poorly influencer vanity books usually do.
This is where I'd love to see Ruby actually putting anything of substance in her videos. I'd love to see her interactions with her agent and the kind of revision requests she's getting at this stage. I'd love to see just what and how Ruby is editing. I mean, she's already revealed that she thinks editing is "mindless" and accidentally deletes crucial scenes to the plot purely because she's just blindly shuffling
tit around and cutting paragraphs at random, but I'd love to know why she thinks it's okay to have a book be completely full of grammar, punctuation and syntax errors in the final draft stage (other than her just not realising her errors thanks to her overwhelming stupidity). And I'd love to know why her agent thinks that's okay, too.
A final draft should be where all those tiny, easy-to-spot errors get ironed out. Ruby's somehow still working on trying to figure out if the book's plot and structure makes sense while not addressing her fundamentally
crappy grasp of things like punctuation.
If I were an agent, and one of the authors I represent handed in draft after draft of a book just packed from cover to cover with errors and issues, one-dimensional characters and clichés stolen from other books, and every interaction with them proved that they had no grasp of the English language, and I then spotted them crowdsourcing their writing by getting her Instagram followers to give her ideas, I couldn't drop them fast enough.
Ruby should've stuck with self-publishing, but her narcissism has her thinking she's entitled to the acknowledgement, accolades and financial success Stephen King and she won't be happy with less than a "big 5" publishing deal. She's in for a world of disappointment, and her agent's not helping brace her for that in any way.
Although you scared me for a minute because I thought you were talking about liking Ruby's book!
