Simon Hayes, author of the Hal Spacejock series is also an accomplished software author as well as SF Novel author. He has a plethora of programs at
www.spacejock.com including an ebook reader -
yRead3, a book database -
BookDB2, and
many other free software tools.
My favorite is his free novel authoring software
yWriter5, which I used to complete a novel during NaNoWriMo (I think I actually used version 4 at the time). Simon is hero to a great many budding novelists for providing such an awsome novel writing environment, and his yWriter thread in their forums is always hot the month before
NaNoWriMo as everyone looks forward to the latest changes that they'll get to use and they complete their novels in the month of November.
So in addition to great SciFi, Mr. Haynes has given SO much more!
BTW, my novel is unpublished and best left that way. After setting it aside for a few months and then re-reading it, I had two reactions:
1. The drivel I wrote isn't worth wasting ink on...not even e-ink
2. Renewed respect for authors like Simon and others who really can tell an engaging story
