Can using editors guarantee good reviews?

My first thought: Why would any book require 4 editors? My second thought: One bad review cannot do this; something else is stopping the book from selling. My third thought was cut short, because my informant sent me a screenshot of the first page. Lo and behold, the answer to this mystery was writ large across that very page. Apparently, there’s also an issue with a trope (disturbing to some) and the author is defending it and basically asking for sympathy.

All I can say is this: Writing is a craft, and those who refuse to learn (and then think they can depend on editors to do the hard work for them) should NOT be surprised if their books do not fly off the shelves. Offensive and disturbing tropes (can’t believe I have to say this) should not be sprung on a mainstream audience.

Also, a note to editors. I know there is the temptation to take on all comers, especially when you are starting out. But I urge discernment and care when taking on your first clients. Not everyone is ready for editors. Not every manuscript is worth your time and effort. Aim to build relationships with authors who will appreciate your expertise, not those highly insecure ones with inflated egos, not the ones who are easily offended or second-guess your every suggestion, those who are unable to tell good writing from bad, who will argue with you and make your job a nightmare.

Be prepared to say no to work that is so lacking in basics that no amount of editing will make it viable. You should be able to tell by looking through the first chapter. Sometimes, you can tell just by the first page.
