True, Todd did not write the Dragon Riders of Pern books, however Todd is working and having his mother's entire works republished in electronic form and hard and soft back form again. The project is a daunting one. My commissioned gift to him was to continue to inspire him to write and continue his work on republishing the Pern series so that future generations can enjoy the stories we have come to love.
Todd has informed me that whereas the Lord of Pern book is truly an amazing work of art, he will not be basing the book in Pern. He told me that the book will be central to a new story he envisioned while at RustyCon. Now whether this will be a short story or a series that deals with this book, we will have to wait and see.
