Almost anyone who has read or written science fiction or fantasy has been inspired by the work of Michael Moorcock. His literary flair and grand sense of adventure have been evident since his controversial first novel Behold the Man, from the stories and novels featuring his most famous character, Elric of Melniboné, to his fantasy masterpiece, Gloriana, winner of both the Campbell Memorial and World Fantasy awards for best novel. Neil Gaiman, Alan Moore, and Michael Chabon all cite Moorcock as a major influence; as editor of New Worlds magazine, he helped launch the careers of many of his contemporaries, including Harlan Ellison, Philip K. Dick, and J. G. Ballard.

Moorcock's first independent novel in nine years is a tale both fantastical and autobiographical, a celebration of London and what it meant to be young there in the years after World War II. The Whispering Swarm is the first in a trilogy that will follow a young man named Michael as he simultaneously discovers himself and a secret realm hidden deep in the heart of London.
