2020’s The House of Styx is the first volume in Derek Künsken’s Venus Ascendant series.
The floating colonies high in Venus’ dense atmosphere were intended to be a triumphant example of the strengths of independent Quebec. Triumphant is debatable; the colonies were definitely expensive. When the four thousand colonists agitated for independence, Quebec was happy to let the colonists go.
The colony is technologically advanced but resource constrained and debt-ridden. The colonists are extremely poor. To survive, they must pull together.
