The Ediacaran Invasion

A fast ride through dizzying scientific extrapolations!


When Paleontologist Karen Regan discovers a machine in 550 million year old rock, she is shocked to discover it appears intact.  She calls on her former lover, Steve Ryle, to supply his revolutionary microscopic robots to explore the interior of the device.  With the help of an engineer, Daltry, the three of them discover more than they dreamed possible:  the machine not only is still active, but it has been waiting to deliver a terrible message — a message that cannot be heard, but must be experienced.  A message that will transform each of them into something more — or less — than human.


How these three explorers react to the gift of the Ediacaran machine will determine whether the human race survives or perishes.


Praise for the “Ediacarian Machine” (which forms the first third of The Ediacaran Invasion, and was published in Analog Science Fiction) includes:


“A very classic skiffy scenario. It has robotics, alien wonders, mysteries to be solved, exploratory adventures, and cosmic scope. It has ethical issues to be worked out. No one is an idiot or a villain, even when they don’t agree. Fans should really like it.  RECOMMENDED.”

—Lois Tilton, writing in Locus
