The Flux is the best kind of sequel: bigger, deeper, scarier, funner. The emotional journey it takes the reader on is just as thrilling as the jaw-dropping wonders of videogamemancy and bureaucramancy. With the 'Mancer series, Ferrett Steinmetz has achieved something rare in contemporary fantasy: a world that feels both truer and more magical than our own. -- Ken Liu, winner of the Nebula, Hugo, and World Fantasy Awards and author of the The Grace of Kings and The Paper Menagerie and Other Stories.
