I included content (trigger) warnings on the Amazon pages of my Wynter Wild books when I published them. I’ve now added a website page that lists them more extensively, linked from the top of the “Books” page.
Click here to read them.
Note that I’ve included everything I could think of using a lengthy list I found online, but not all warnings apply to all books in the series. It’s also worth noting that some of these issues are referenced (for example, as past events) but aren’t “on the page” as such, and that overall I don’t consider the books to be explicit when it comes to sex or violence.
