This book is...ok. And didn't age well. A decent first introduction to the Virtual Adepts. It covers who they are, the origins of the Digital Web via Alan Turing, and the so very important to future Mage supplements Dante through the course of the book. On the other hand, the primary Virtual Adept Chantry has 56 kpbs internet (or worse, intranet), and rotes are all uniformly half a megabyte, which is itself strange that they'd all be the same size.
The factions are decent, and represent several different approaches to "Everything is Data" (to use M20 terminology), the epistolary format works well here, though it's so interwoven with the Digital Web that the whole book feels incomplete. Fortunately, the Digital Web book also exists, but reading this without the other would leave a lot missing.
