I am reading this book called Rhetoric of fantasy. Its author argues there are three (actually four) kind of fantasy from how the fantasytic is accessed by the reader. Portal, when the main character travels to the fantastic. Immersive, when the main character is immersed in the fantastic. Invasive, when the fantastic leaks in into the 'real' world. Shockingly enough, she argues that LoTR is a portal fantasy, or at least it has its structure, as it starts from a mundane world that slowly opens up to the fantastic. As opposed to Steve Erickson's work, where the reader has to figure out all by himself... Have you read it? Would you? If you did, what do you think?
