Here is a snippet of the prologue I have written up for this idea which I randomly titled Second chance.
By 2047 humans as a race became almost extinct after the use of volitile chemical weapons and acts of brutality.
Little did we realise we were being watched at a distance from an alien species.
The aliens came to our planet and began to harvest what was left of the human race, their intention to save the humans from them selves and set up a new civilzation under their supervision and control.
The aliens knowing how volatile the human species are implanted humans with mood monitoring chips with the intention of controling and preventing violence.
he aliens were successful in their attempts, the human species began to grow in numbers even though there has been no child in sight. Pregnant women were taken away by the aliens to unknown locations, they were never seen again.
The story would follow a man who begins to question their existence and the purpose.
The setting would be in space and on a kind of artificial world that the aliens created for the humans.
Humans will have a mood chip attached to the back of their head (would be a custom mod kind of like a square light that changes from green to red depending on the humans mood). They are monitored by aliens, if a humans mood changes the chip alerts them and aliens swiftly intervene and take the person away for processing.
The humans only contact with the aliens is through one man who they have never seen in person, but he brands himself as the humans president and their channel of communication with the aliens. Humans contact him through comms available in their living quarters.
Of course not all is going to be what it seems.
This is pretty much all I can think of right now. I can tell though that this could end up being quite a big project if taken up
