Worth noting the author's warning on TMoPI: "This online novel contains strong language and extreme depictions of acts of sex and violence." This is very much not a routine notice, and it runs the gamut from elder abuse to self-mutilation to suicide to torture to necrophilia to drug abuse to underage sex. It is fascinating, but it is a story of deeply unhealthy people doing deeply unhealthy things.
I say this as someone who appreciated it enough to buy it hardcopy.
