Guys...
As someone who's read Nick's book, I'm calling bullshit.
1. It's very obvious that this takes place on Earth. Just because a city or technology doesn't exist in the real world doesn't change that. This was never confusing.
2. Reducing the slang = good. Removing the slang = stupid.
Also take a good look at that comment from another reader. He read some of the book. No wonder he was confused.
As for exposition, everything you need to understand the story is in the book. The history of Nevermore and its people, where Dillo comes from, why he is the way he is, character backgrounds. It sounds like this guy wants it all shoveled up-front, which is how you write a shitty beginning to a book.
So I'm going with CG--not the right publisher. I told you this would be a tough sell; anything unconventional is.
On self-publishing:
This is the future of media distribution.
Times are changing. Music, books, comics, video games... The big companies don't know what things will look like even 2 years from now. Take a look at our own forum's Tinwhistler. He said if his sales stick, he'll be pulling in $25k for his book by year's end. That's pretty much all eBook.
Also, if you publish only through eBook, that means you haven't used first print rights. That means that if a company finds your book (including Amazon publishing, who have done this many times since self-publishers began popping up on the Kindle) they can still buy those rights and print the book, with all the traditionalist bells and whistles.
And then there's situations like Harlequin publishing, whose recent publicity came from cheating an author, giving her 2 cents per sale, or Archaia, who has let the second volume of Gunnerkrigg Court remain out of print for years, with nothing the author can do about it.
So yeah, it might not feel "legit" because centuries old companies have an interest in telling you how it's supposed to feel. A decade from now? Even those companies don't know how things will be. I do know that within the past few months they were sued by the U.S. Department of Justice for price-fixing; essentially screwing over their authors and customers. Self-publishing, kickstarter, KDP--these things are cutting out the middleman in media. It's letting people decide what they want to read rather than having a publisher tell us what we want to read.
The downsides of self publishing are that 1. you're putting yourself out there and that's scarier than letting someone else put you out there, because it's all in your hands to click those buttons. 2. you're the one telling people you're out there; or you're getting other people to do so because you let them read your book and they want others to read it too.
