I don't read much science fiction, and I attribute my slow start in reading this book to that fact. But once I began to see the situations that the large cast of characters were in, my interest in the story grew, and it became a read page-turner for me.
The idea that someone could transfer their mind into and out of an electronic device is a common idea. I've never considered that if the device was then upgraded to run faster, the more computational cycles in a shorter amount of time would have the effect of slowing time in the real world, so that the digital mind could experience days and weeks (or more) when only moments have passed in the real world. That was a real eye-opener to me, and it integrated well into the story.
Most of the characters were engaging, although the authority figures seemed to me a little stereotypical. I thought the book was well-written, and I would recommend it to anyone who likes a futuristic story and would not be put off by some detailed descriptions of the technology used.
