This dystopian novel is set in the not-too-distant future, when print is dead and and much of the population relies on implantable devices called "memes" to consume information and communicate with each other. That sounds unsettling enough, but things get really scary when a virulent "word flu" is unleashed upon the population: the infected lose their ability to produce or understand speech. Much of this book is written in the form of diary entries that the characters write in their efforts to first fight off, and then recover from, the linguistic illness. A fun ride from start to finish.
