Yes I have. In many ways I found it to be the weakest of the Shadow books, particularly in how it keeps refering to aspects of the characters' natures and history in the narative in a repetitive and simplistically explicative fashion. I also found myself wincing at some of the technical computer details, like suggesting that the only thing a sysop would have done to monitor the online activities of a known powerful psychopath is attempt to capture keyboard input (without noticing for weeks that the info he was getting was garbage). Ignoring the potential for having applications keep logs and capturing information out of the mail queue or simply watching outgoing packet routing/traffic loads from individual machines at tracked times was a pretty large lack in my opinion.

I also felt a little bit longer denoument would have been nice. The book ends pretty suddenly. I don't find myself interested in a whole 'nother sequel, but I want to know what happens immediately next in a few people's lives. (so I will probably read another sequel if he puts one out, hoping it resolves that issue... but I''m not sure he would write it)
