First, you’re a stellar book reviewer! I love psychological thrillers. This one sounds interesting. I’m not so much into gruesome details but I like the mystery part of it. I don’t see any harm in providing a trigger warning even though as an author you could be shooting yourself in the foot if a reader gets completely turned off from purchasing the book. But, I think if the description does its job on the back cover, it’s to each his own.🤷🏽‍♀️
