It was Brian Purcell who suggested we might celebrate our 100th book with an anthology of 100 authors. To reward Brian for his great idea, he got the massive and thankless task of editor. The resulting anthology is a treasure and a testament to both Brian’s tenacity in herding the many Flying Island cats—some, whose works stretch right back to the early days of 2010 and some slotted for future publication, gathering, collating, nagging, proofreading, and finally presenting the fine collection here.
