Note: Published as by R. A. MacAvoy alone. According to a January 1, 2016 post on R. A. MacAvoy's blog: "This is my only collaboration, though it was published under my name. I am still ashamed of this misjudgment, which was largely mine, as I did not bother to argue the point of it being the work of Sharon Devlin and myself before submitting it. I assumed that the book would stand by itself, and that her name would be obvious and automatic. Instead I was told by Bantam that they would not publish a collaboration because such didn't make money. Had I been older I would have thought to say that KELLS wasn't the book I owed Bantam, and that I would sell it to another publisher and deliver them the book I owed next year. But both Sharon and I needed the money and I was unaware of my rights, so she was denied credit for a book that is at least half hers." The dedication in the 2014 edition reads: "To Sharon Devlin, who was the inspiration for this book, and who worked with me and guided me every step of the way."
