Amber Sea

Life can exist anywhere. As long as you keep it secret. An interplanetary civilization of the dead should be the best kept secret of all - providing you choose your victims wisely.
On the raised surface of Venus a secret narco civilization is tunnelling its way to independence from Earth. Outside is dangerous, but a thousand more years of venera-forming will allow free-breathing settlement in the amber sea swirling around the planet.
But Venus carries a secret. A parallel Earth of trafficked humans emerges where it shouldn't exist. Enter Mei, a paternal orphan, and Maddox, a smuggler on the run. They settle the scores of their ancestors. In doing so they draw the line between hero and villain so sharp that it threatens to end life on Venus and transform the solar system forever.
