Not Sand, Not Sound is meant for the avantgarde of readers who believe in time travel, in quantum logic, in the apocalypse, in a blue and red side of the brain, speak Latin and therefore know more than the rest of all.
There are a lot of pages of the book free to read on Amazon. You will get a fitting impression … then decide for Not Sand, Not Sound. There is more truth in it as you might see right now. I put my knowledge I gained in over 40 years of computing and brain research to a cocktail of the future, copied some nonsense from different sources and added some surreality.
