It's short (well 175 pages) and sweet and sci-fi and computers and singularity and sex and violence and violence and it's fucking lovely. You can read the entire thing on his site: http://localroger.com/prime-intellect/mopiall.html
I highly recommend it.
If you guys have any interesting recommendations, I'd love them, since I just got a Kindle Fire ( :DDDDD ) I prefer shorter things because my attention span is spastic and I usually end up starting something new rather than finishing a longer book. I love sci-fi but have read most of the generally accepted "best" ones. I am slowly making my way through this reddit thread because there's some ones that show up there I haven't read yet.
I am especially obsessed with singularity right now (I read Kurzweil a couple weeks ago) but I trust your judgement for good reads.
Just finished it, amazing. Major Spoiler:
At the end, I was half expecting Prime Intellect to save Caroline because she got P.I's attention when she said it's name and what she had been through since the 'new world' making her human again or something
