Well, after last month's first foray into professional editing, I dove straight off the deep end. I reached out to four different editors, asked them for sample edits (some did a page, others a whole chapter), and then compared their feedback. 

Funny how much you can tell about a person just through email correspondence: one editor's form response started with her qualifications (with publishers from 20 years ago).

Recently, I hired a developmental editor to read my synopsis and the first 4,000 words of my story (first page is above). These first pages often require multiple rewrites.

Perhaps you've never analyzed the first line or first chapter much, but there is tracked and subtle psychology at work here. My job as a writer is to "hook" without you noticing, "Ah, I see what you did there," or pause because too much/little info is pulling you out of the story. 

To catch you up, for the last few years I've been writing sci-fantasy; a sub-category of sci-fi. Dune and Star Wars fit here, "a hybrid genre blending advanced technology, space travel, etc. with magic, supernatural powers, etc.". 

Attempting to wrestle a collection of scenes into a novel with young children while co-running a clinic with Kyle—well, it happens seasonally; almost none in the summer, lots in the winter, and variable shoulder months.
