For many readers, the feel of a fantasy world lingers long after the plot has faded. The key ingredient, says author R.J.

Author Seth Dickinson introduces five mind-bending novels that give a fresh take on the idea of the alien: invasions that are so other in their motives, methods, or meaning that they push us to the edges of human understanding.

Solarpunk fiction is a form of climate fiction, but by focusing on the changes we could make, it can move us past climate anxiety, says author and editor Sarena Ulibarri.

A fantasy ‘classic’ is a book that enables a new kind of story to be written, says fantasy scholar Matthew Sangster. He introduces five classics, and explains how they both build on and subvert our shared stock of stories to create wonderful new worlds – worlds that are not made to be admired from a distance, but rather to be lived inside, and shared.

H. P. Lovecraft has been hugely influential on many leading names in speculative fiction today, and is also frequently adapted – and frequently subverted. Jeffrey Weinstock, co-editor of The Age of Lovecraft, introduces five stories that best illustrate the themes and range of this influential figure: the anxieties, the typical Lovecraftian twists, and the ‘cosmic indifferentness’ that set his work apart.

Cyberpunk focuses on the near future, and on the impact of technology on human affairs, says Jared Shurin, anthologist and editor of The Big Book of Cyberpunk.
