Imagine, if you will, an America where the armed forces are spread all over the world on "Peace Keeping" duties. Imagine further if these forces left and the situation in America deteriorated until the disenfranchised members of the far southern states rose up in mass rebellion against the state. Imagine further that this turned into a second civil war that divides the nation and leaves a DMZ, that is the island of Manhattan in New York, that separates the two sides.
This is the fictional setting of DMZ. A young photographer Matthew Roth is sent into the DMZ with a team of reporters and soldiers only to be left there by himself with only his wits and equipment. He them send reports to his network about daily life in the DMZ.
The world as it is portrayed is highly believable, the people are portrayed in a sympathetic yet realistic way. Within the DMZ are stories of horror, love, heroism, depravity in fact everything that is part of the human condition. The people are abandoned by BOTH sides in the conflict and live their lives in constant fear.
I fear that this book will be compared to Transmetroplitan, mainly as it is Science Fiction and has a journalist as the main protagonist - however that is as close as the two actually come to each other. Transmet was all about finding/speaking the truth through whatever means, with this the truth is all around Matt as he reports what is going on. Spider manipulates everyone, whilst Matt is manipulated for other peoples ends.
This is the finest piece of near future writing (in any form) that I have read for several years. Buy it now and see what lurks within the DMZ.
