"Cyberspace doesn't have depth", Bartlett says. The Internet is much more that Facebook, eBay and Google. It's also child pornography, drug dealing, murder requests and political extremism. "The Dark Net, inside the digital underworld" – a book by Jamie Bartlett – is an interesting book that will show you what's under the surface and bring you to the darkest sides of the net. Each of the book's nine chapters introduces you to a different character, such as Taaki – a genius coder and architect of Dark Wallet – or Paul, a polite and charming fascist, and Michael, a family man convicted for downloading a hard-drive's worth of child pornography.
