Patrick Arnesen literally breathes life into the software he's dedicated his life to creating. In this novel, he explores what happens when the people you love decide to digitally remaster themselves by dumping their minds into a computer simulation.
I enjoyed the adventure and mystery parts of the story, but I most liked the philosophical musings on conciousness, software, and just how much of a gap there is between the two. There were even a couple of good surprises along the way.
