The Helmet of Horror — Victor Pelevin

When Ariadne helped Theseus escape the MInotaur's labyrinth with the aid of a ball of thread, she led the way for the bewildered victims of a twenty-first century minotaur. Trapped in an endless maze of Internet chatrooms, a group of mystified strangers find themselves assigned obscure aliases and commanded by the Helmet of Horror, the Minotaur himself. As they fumble their way back to reality through a mesmerising world of abundant information but little knowledge, we are forced to wonder - can technology itself be anything more than a myth?
