Gavin Corbett's new novel Green Glowing Skull is a half-crazed brain-shunt of a trip around the dream world, the spirit world, the cyber world and a woozily recognisable real world. A darkly comic tale of mythologies, machines and the metaphysical swirl, it’s a decent third effort from Corbett that, with a fair wind and a bit of mercy shown towards it, and all other things being equal, will pick up some good reviews and find some kindly readers. Sure, all you can do is hope.
