This is a list of my favourite authors in no particular order – just as they come to mind:
Kurt Vonnegut Jnr
Philip K Dick
Arthur C Clarke
Yuval Noah Harari
There are many, probably hundreds of others on my shelves and that I have read. But these are the ones that come to mind that have enthralled or inspired me (I left out my Sci-fi ones).
So – who have I missed out that you think is essential?
