Book critic Alisha Tyson talks about Speculative Fiction - what is it, and what are the genres that come under this umbrella term, and why is there a debate about speculative fiction vs. literary fiction.
She recommends The Weird: a Compendium of Strange and Dark Stories edited by Ann and Jeff Vandermeer
Some authors to explore if you want to look at some different genres that branch off from Speculative fiction:
Ben Okri - an author who writes 'magic realism' but prefers to have his stories known as dream-logic that discus a philosophical question.
Kelly Link - Slipstream, magic realism
Shaun Tan - Surrealism, allegorical fiction particularly his book, Tales from Outer Suburbia
