Interactive fiction isn't a book at all, but rather a description for a type of software environment in which players communicate and interact with one another via text-based commands. While everything is in text format, plenty of descriptive text is used in interactive fiction to give all participants a creative and accurate mental picture of their characters and the surroundings within which their characters are based. There are many popular types of interactive fiction, the more common ones including Choose Your Own Adventure and DSL-Mud.org.
The most basic pre-requisite for an interactive fiction game is a computer, since the majority of interactive fiction games are run off of computers. Secondly, you will need an active internet connection, as the majority of games are played online. The advantage is that you can play an interactive fiction game with anyone anywhere in the world. The disadvantage is that you will need a stable internet connection; a loss of data transfer can result in the loss of data for your game. To find an interactive fiction game, search Google for popular text-based games.
