Laredo Space Base hadn't sent a ship to Earth for hundreds of years before the Project Deep Green survey craft was launched. Only one thing was known: the planet humankind had so long ago vacated was a wasteland with nothing on it but poisonous flora and small, murderous denizens.
That's what they taught astronaut Ferrer Burgoyne and as a result he was totally unprepared for the teeming jungle stretching farther than his eyes could see. He was even moer unprepared for the slightly green humanoids who greeted him. Obviously the scientists of Old Earth had done more in their labs than just mess around mixing human and plant cells. As sure as Ferrer Burgoyne was an astronaut the new men of Earth were the descendants of those hidden, forbidden experiments.
How then could Burgoyne continue his mission: to defoliate Earth with the deadly chemical Deep Green and prepare Earth for the return of his species
Doris Piserchia (1928 - )Doris Piserchia was born in Fairmont, West Virginia, where she grew up as part of a large family. She attended Fairmont State College and worked as a lifeguard while earning a teacher's degree in Physical Education. Upon graduating in 1950, Piserchia realised that she didn't want to become a teacher and so instead joined the Navy, where she served for four years. It was during her time studying for a Master's degree in educational psychology at the University of Utah that she discovered science fiction and began to write, although her works were not published until 1966, beginning with the humorous short story 'Rocket to Gehenna'. Despite her military experience, age, and preference for older SF, she is often associated with the New Wave, with her works being described as 'darkly comic' by admirers. Piserchia has not published any new work since 1983.
