Blackthorn of Mars rides again!

Blackthorn, Princess Aria and Oglok ride again! A young man desperate to save his sister from the raiders who kidnapped her to slavery... An ancient undead released after half a millennium... Four sorcerous First Men who will kill half a world to keep their darkest secret... And three champions who will stand for Mars against horror and tyranny--or die trying! Join Earth General John Blackthorn, Princess Aria of Mars, Oglok the Mock-Man and an ever-expanding cast of rebels, monsters, magicians and villains battling to solve the mystery of the ancient Harmony Spires. From award-winning author, I. A. Watson comes a new novel in Van Allen Plexico’s Blackthorn universe, where magic and technology are one and Humanity must face its ultimate challenge.

Longtime denizens of the Pulp Factory may recall the multi-author SF setting put together by Van Plexico when we were all much younger. It's post-apocalyptic Mars by way of Kirby and Burroughs, and there was an anthology. Then Van made me do a novel. Then I wrote some weekly (or was it daily?) promotional shorts for the novel. Then the shorts became a novel. Then Van threw away his computer with it on (this is extreme editing). Now, much revised and again expanded, said novel has appeared to drag you back to the Red Planet where science and sorcery meet swords and swashbuckling.

Anyway, if your SF taste runs to matinee-cliffhanger and warring arch-villains vs a princess and her hero then you may wish to give this a look. It's there on Amazon.
