Public Domain - The Tunnel Issue
To all those for whom Jules Verne's Journey to the Center of the Earth was not enough, we now recommend the Public Domain Book. This book also takes the reader underground and offers a colorful cross-section of what is happening beneath our feet: From Naples' network of caves to the so-called cataphiles under Paris to Moscow's metro, the spectrum here runs the gamut. There are even reports of graffiti writers who prefer to paint underground!
These and other stories of places whose existence has so far remained hidden from us make the book an entertaining and interesting read.
