Failbetter’s collection of ‘immersive fiction’ continues to grow via its Storynexus platform but I haven’t found anything in the collection quite as gripping as the bizarre demon-Dickensian sprawl of Fallen London. Until now! Black Crown, the first published work from author Rob Sherman, has found life as a Storynexus experiment thanks to a collaboration between Random House and Failbetter. It’s free to play, although some (presumably) optional branches require the purchase of Nex, the currency shared across the Storynexus platform. I’ve only spent an hour in the word labyrinth so far, but I’m hooked. As well as being adept at squeamish body horror, Sherman shows the mark of a supreme builder of strange worlds.
