The Alsiso Project concept was conceived by Andrew Hook in response to a typing error by writer Marion Arnott (she meant to write 'Alison'). He subsequently invited 22 fellow speculative fiction writers to create short stories about that mysterious name. All the tales included in the book are titled 'Alsiso' (or with variations on that name), with the different contributors turning their minds to such subjects as bogeymen, places, viruses etc. The Elastic Press website says of the book: 'The Alsiso Project is a unique anthology of expression interweaving coincidence with commentary, mystery with knowledge, and illusion with fate.'
