Panopticon is a great supplement for Eclipse Phase that discusses three separate areas of the game setting.
Part one explains how the transparent society of EP came about, how it functions, and how people function in it. There are sections about how identification works when individuals can change bodies at will, the ethics of a transparent society, and surveillance/counter-surveillance technology. Part two details the different kinds of habitats, the various systems contained therein, and a general discussion of the difficulties of life in space. The last part is a great discussion on uplifts, including more information on the various types (including several new ones) and the social issues surrounding them.
As with other Eclipse Phase books, this one starts out with a short story and puts all the game related information in the back. This title is a great resource for GMs and players alike, as each section sheds a lot of light on how various parts of the EP setting work. Anyone interested in playing as an uplift would do well to read the relevant section of this book, as would anyone interested in playing as a hacker.
Panopticon is a great read, even if you don't intend on running or playing in an Eclipse Phase game. It is well worth the $10.00 price tag.
