Excellent.
A True (male, or lesbian I suppose) geek's dream story: not only does he happen to meet someone who is also into data visualisation - as one does - but their combined tech-skills provide a paradigm shift for a group of, for want of a better term, adults.
And I agree with Steve about this being fantasy and sci-fi (though the fantasy part is fairly hammered home - the exact method that story=immortality are kept vague but important).
I have to say that the setting of the story - post(ish) recession, the use of Google, modern day - gave the story a slightly creepy feel. Like those Japanese automatons that are not quite real, and so emphasis how strange they are, this story emphasised it's strangeness by, in most other respects, being exactly like places that exist today. We really, possibly, might just get a job in a dodgy old bookstore and spend our time dreaming of googly data visualisations.
One part of the story that I wasn't so convinced by was the possibility of someone really creating a mental, or otherwise, plan of the book buying and habits so that it would create a face. With a computer, speeded up, simulation for sure, but really having the whole process in your head like that.....I dunno.
But I loved it. And I want to meet more people with BAM! on their t-shirts.
