I very much enjoy Mr. Donaldson's works, especially the Gap Series. I'm interested in creating an open-ended PC space simulation which would accurately reflect the universe of the Gap novels. Problem is, I can't seem to find a way to contact Mr. Donaldson for approval. Without his approval, the project is dead in the water.
Does anyone know of an email address besides the publisher (which is my last resort, since they receive a great deal of emails)?
Thanks in advance for any help.
