What a brilliant read this has been over lunch 
I've no intention of trying to become a professional author right now, since I'm far too sensitive to be critiqued, but I may one day try to submit one of my works.
I've written about three YA novels over the past eight years and 5 short stories (for picture books, but i can't even draw a matchstick man).
My YA novels are part of a series. I'm halfway through writing the first draft of the fourth one (it's dire right now, mind you). I love them and was all set for submitting the first three chapters of book 1 to an agent when i read a lot of 'don't bother' type threads on various CW forums.
Apparently publishers aren't interested in a series from a debut/unknown writer. My first book doesn't end on a cliff hanger. I've written it in a way that it could be published as a standalone novel if needs be. But i still feel uneasy about submitting.
So can i ask your opinion on a series from a new writer? Is it a total waste of time? Should i (if i ever submit) mention in my opening letter that it's part of a series, or would this put a potential agent off?
It also weighs in at 85,000 words. I've read that this high a word count won't be considered from a new writer for a YA novel. Should i try getting it down to about 75,000? I've already chopped and changed it about 50 times over the years. After the first draft, it think it was something like 125,000 words!
Also, I've read that you shouldn't just submit to one agent at a time. How many would you recommend submitting to?
What happens if two authors request a full MS, then they both want to represent you? How on earth do you choose? And will they both feel messed about by you if you need a while to decide?
And how much power does an editor have? Are you ever allowed to disagree? And how does the editing process work? Do you need to travel and meet with them in person, then they send you home to make the changes? And then you email the revised MS to them?
And a few other questions for those of you who tour.
How do you afford it? Does the publisher/agent pay for your travel and hotel? If so, do you ever need to pay this back from future sales? How high is the impact on sales if you don't tour?
What happens if you're self published? Can you not tour unless you're making loads?
How does the touring tie in with other responsibilities such as family, work etc. Are the dates negotiable? Or is what the publisher says goes? Are you ever allowed to take your children with you on a tour? If so, would a publisher pay their expenses too? Then what do you do with them once you're there? Find a new CM every day?
So sorry for all the questions! They've just came tumbling out.
