OK, the tales are twisted, but not really NSFW. Videos might be NSFW, so might pictures. (My Kindle epub has no pictures). Generally speaking, if you are reading some of these stories at work, you won’t get busted. Just don’t read them on a “parents take their kids to work day.” If you do, don’t let your kids read over your shoulder.
Burnt Tongues is a collection of short stories edited by Chuck Palahniuk. Note the subtitle: An Anthology of Transgressive Stories. To get an idea of what transgressive as a genre is, I refer to the dictionary that comes with the Amazon Kindle Application for PC under special usage:
of or relating to fiction, cinematography, or art in which orthodox cultural, moral, and artistic boundaries are challenged by the representation of unconventional behavior and the use of experimental forms.
This is a qualified definition, meaning a writer in this genre can use other phrases, such as minimalist or grotesque. The editors of this volume explain this in their forward. In The Power of Persisting: An Introduction, Chuck Palahniuk adds thoughts on how this genre came to be so unconventional. His introduction will soften the blow for unprepared readers.
That’s about as much warning as I can give.
