John Dalmas has published 27 primarily SF novels, mostly with Tor and Baen. In his 80s now, John has decided to make his back catalogue available as free downloads from his site.
I haven't read much SF since the 70s and wasn't familiar with John's work. I feel incredibly honoured that he approached me, praising a story of mine he'd read. Since then, we've swapped a few emails and I've come to know a wonderful man.
If you check out his site, I hope you'll read his articles about the aging process. They are extremely touching and fascinating in their courageous matter-of-factness.
He's a good man, doing a good thing.
