I've been trying to help out a reciprocal reviewer (offsite) on a particular point for a couple of weeks now and so I thought it would be beneficial to turn to our small writing community on this forum for advice? What seems out of sight for me maybe easy to see for others 
Also it's too quiet on this forum so :cool - *hands out tin foil hats labeled - made in the Bermuda Triangle - spinning compass not included*
Without going into much detail, the storyline in question involves a body switch to an alternate Earth that is almost identical but not quite evidenced by the technology that allowed such a swap to occur in the first place. Impacted genres are: fantasy, science fiction, and romance.
When I originally reviewed it, I critiqued it on the specifics and at a micro level not really at an overall big picture overview. After having reviewed the first 6 chapters I have come to agree with the author that the chapters are lacking something vital to catapault the reader to the next chapter. I'm stumped on what that is.
It's written in 1st person POV so with that comes the territory of a lot of self introspection and thoughts. The first chapter is IMO around 97% "fluff" with a decent hook at the end where the character falls unconscious to wake in world B. I will define "fluff" here as describing in detail the daily events: getting breakfast ready for spouse and kids, seeing kids off to school, cleaning up at home, etc. Chapter 1 was intended by the author to set the tone to the reader of a very ordinary day in an ordinary housewife's life. The author wants to go small potatoes and build up over time to larger events. If you are familiar with the idea of the snowflake writing format then you know there will be 3-4 large events that the entire novel is structured around as they build up to those points - I think that is what the author is trying for.
Chapter 2, 3, and 4 involve waking on world B in a different person's body and having to figure out what is going on etc. Chapters 4 and 5 also focus on home life in the new body with the family of the person swapped. On revisions the author incorporated feedback on playing up the WIM card (woe is me) and showing bouts of depression, self doubt, and longing for the "other" life on world A. While this helps, WIM can't carry the chapter interest alone. The author wants to set chapter 5 on fire and bury the ashes decrying it as "boring". Chapters 2-6 are running around 70% fluff, 20% WIM, and the remaining 10% suspense/danger of being discovered composition.
My ideas so far which have been refused to give you an idea of what not to suggest?
- An organization that brought MC to world B is now actively searching for her.
- MC runs away from "home" to go back to original home not knowing she is no longer on world A although she's seen some technological differences and is becoming suspicious (clocks that run on 24 points vs 12, cars with unheard of manufacturers, hospital used scanning technology clearly not anything seen before, etc.)
- switching POV for a chapter or 2 and show the "other" person's experience in the MC's body. The author is uncertain at this point if she wants a full A to B and B to A switch. Might go in the tragedy direction and other person ceases to exist.
The author's strengths: expert grammartician, detailed plot written out in advance with character designs included, writing is efficient and emphasis is on sense discription (sight, sound, smell mainly).
weaknesses: heavy on descriptions at times bordering but not quite into purple prose territory. Too much fluff writing, too caught up in the details and prefers slower pace. When I say slow I mean stand here and watch this leaf find enough wind to move across the lawn. Not quite a snail pace but not a quick walking pace either.
The only larger plot point the author revealed to me at this point for the future is - a good guy image boyfriend who in reality is a stalker-fiend character to be introduced in later chapters. I have a feeling this won't occur until chapter 10 or later.
Any ideas on what can be done to fix the issue? How much fluff should be allowable? Zero, 10%, 50%, have no idea? The author's chapters run 5-8k words on average. The prose description contributes significantly to this.
My worry is if not enough interest is derived before chapter 10 no one will care since they will have stopped reading.
Have you seen any writing that follows this pattern? If so, do you know how the author fixed it, if at all?
Are there any points that the author seem to you to be adamant on not incorporating that actually necessitate they do? In short, if I have to risk the author's wrath, and push back on what strategy or points do you think I should do this with?
