Triggering to what? Do you have a specific anxiety or post-traumatic condition?
Nothing is “triggering” in a general sense. Some things might trigger some specific response for some specific people. As in, a book where spiders appear might trigger a stress response from someone who suffers from arachnophobia.
It’s impossible to track all the possible responses people might have to each piece of literature.
If you just want to shelter yourself from potentially disturbing literature, that’s a choice you can make, but using the term “triggering” isn’t really accurate or appropriate. And don’t be surprised if doing so further tenderizes your sensitivities.
LOL if the average american read 50 books a year, we would live in a far more sensible world.
