While it’s a challengingly academic read, The Postmodern (New Critical Idiom) by Simon Malpas is an excellent introduction to and exploration of postmodernism. The book serves primarily as a review of literature, drawing upon some of the most important works in postmodern thought, and showing how each work shaped the discussion. Malpas’s stated goals for the book is to demonstrate what postmodernism is, but along the way he does an admirable job highlighting its strengths and weaknesses and placing it within the contextual framework of a still quite-effective modernism and realism.
