Dave lives with his wife Rita and hisChristopher, age 12, in Westminster Maryland, USA. Although Dave is the publisher of the Anna Grayson story, the work was created by his daughter Katie O'Brien who passed away in March of 2005 at the early age of 13. Katie worked on Anna Grayson and The Order of Merlin for two years and wrote most of the text while going through her chemo treatments for Leukemia in the hospital.She finished the book just six days before her death. Katie and Dave were a writing team. Katie was the author, and Dave was her editor and beta-reader. Katie has published several short stories over the years, leading up to her work on The Order of Merlin.
"This book is dedicated to my beautiful daughter Katie, who worked so hard during her struggles with her health. Sitting alone together in the hospital day after day, night after night, we started this book because of her love for Harry Potter, and to help her take her mind off of the pain of her many treatments. I am very proud of my daughter, my little red head. Her imagination and courage were the foundation of this work, and the magic that keeps her loving family going. May God hold her in his loving arms until the day she comes to be again." DaveO
The book is based on the work by J.K.Rowling, and the Harry Potter series.
