New Editor - Do I ask if they have a “style guide” or “house style” that I can follow?

Problem: I am a freelance editor hired by an indie author for a completed first draft of a novel. The author is a regular client for me, but is using a new editor for line edits as the manuscript is "more literary" than the prior works I have edited. This new editor has suggested changes that are distinctly different from my suggestions.<br><br>Example: For the most part, I have tried to follow Chicago 17 (I know it’s now 18, but I have 17 on my phone), and I have tried to be consistent. I have, or so I thought, followed the house style of the publisher for this work. However, the new editor, for many of the same areas, seems to be following AP. I only know this because I am familiar with AP. The issue is that the new editor made many changes that I do NOT recognize as a particular style, but that also fly in the face of the choices that I have made.<br><br>Example: The new editor keeps capitalizing “goddamn” in the dialogue. I kept it lowercase, and the author accepted it. I can only imagine that the new editor has capitalized it because it is in dialogue and a character is using it as a proper noun. In other words, it is an invocation, where the character is asking God to damn an action, thing, etc.<br><br>Example: The new editor is capitalizing a name that is completely made up, but that in my, and the author’s, opinion is not a proper noun. It is a metaphorical name given to the weather. The author specifically asked for it to be lowercase everywhere it appeared. The new editor capitalized it.<br><br>What to do: I’m not sure what to do at this point. I am a freelance editor, so it is up to me to decide what I “charge on” and what I just roll over on. If they get close enough, I will just roll over and call it a day. But if it’s egregious enough, I will put my foot down and have a discussion with the author. I only get paid for my time, so it is up to me to decide what is worth the time to discuss and what is not.<br><br>I thought I would throw this out here and ask if anyone has any thoughts.<br><br>PROPOSED SOLUTION: I now plan to email the client and ask if there is a style guide in place or if the new editor has a house style that I should be following as I complete my tasks? I will also politely inquire as to whether they have directed me to follow a particular style guide that I am not aware of, and if so, ask for a copy of that guide so that I can follow it.<br><br>Thanks in advance for any input, thoughts, or ideas.
