Book excerpt: Now expanded: The definitive visual guide to writing science fiction and fantasy—with exercises, diagrams, essays by superstar authors, and more. From the New York Times-bestselling, Nebula Award-winning author, Wonderbook has become the definitive guide to writing science fiction and fantasy by offering an accessible, example-rich approach that emphasizes the importance of playfulness as well as pragmatism. It also embraces the visual nature of genre culture and employs bold, full-color drawings, maps, renderings, and visualizations to stimulate creative thinking. On top of all that, it features sidebars and essays—most original to the book—from some of the biggest names working in the field today, among them George R. R. Martin, Lev Grossman, Neil Gaiman, Michael Moorcock, Charles Yu, Kim Stanley Robinson, and Karen Joy Fowler. For the fifth anniversary of the original publication, Jeff VanderMeer has added fifty more pages of diagrams, illustrations, and writing exercises, creating the ultimate volume of inspiring advice. “One book that every speculative fiction writer should read to learn about proper worldbuilding.” —Bustle “A treat . . . gorgeous to page through.” —Space.com
