Wish you had a new episode of Radio Active to listen to? Never fear, a new one is on the way, but in the mean time you can listen to Episode 17 of The Secret Lair podcast, in which I talk with hosts Chris Miller and Kris Johnson about S.M. Stirling's alternate history/modernized pulp novel The Sky People.
In this book, Stirling creates a solar system in which Venus and Mars were habitable, just like they were in the pulps - Venus is a jungle world complete with near-human civilizations and dinosaurs, while Mars is a dying desert planet populated with ancient civilizations. Unfortunately, we found the premise to be a lot more interesting than the actual book.
