Pirates of Venus

The shimmering, cloud-covered planet of Venus conceals a wondrous secret: the strikingly beautiful yet deadly world of Amtor. In Amtor, cities of immortal beings flourish in giant trees reaching thousands of feet into the sky; ferocious beasts stalk the wilderness below; rare flashes of sunlight precipitate devastating storms; and the inhabitants believe their world is saucer-shaped with a fiery center and an icy rim.
Stranded on Amtor after his spaceship crashes, astronaut Carson Napier is swept into a world where revolution is ripe, the love of a princess carries a dear price, and death can come as easily from the blade of a sword as from the ray of a futuristic gun.
