The novella Darkness San Francisco takes place in a world with no power. The world lost all electricity after a solar storm destroyed grids around the globe. Four full-length adventure romance novels were written in that post-apocalypse dystopian setting (the Darkness Series). They detail the trials and tribulations of a group of strong lesbians who must endure together to not only survive but thrive. 

Settling in the small town of Astoria, Oregon, they face many external and internal challenges, but in the fourth novel, Wind Dancer, a new evil emerges—a pirate king named Captain Poissoit who is pillaging the West Coast. Listening to the books in the order they were written is strongly recommended: Darkness Falls, Darkness Remains, Darkness United, and Wind Dancer. Although each is a complete story, they are much more enjoyable, as the listener gets to know the cast of characters as they appear in the series.

In Darkness San Francisco, two main characters from the series, US Army Major Grace Hamilton and her partner, Ship Captain Meg O’Grady, set sail from Astoria to track down the pirate king and bring him to justice. They will chase the outlaw on their ship, Wind Dancer, to his lair in San Francisco, if necessary, to capture him. The Darkness San Francisco novella focuses solely on their adventure. Although much still happens in the city of Astoria, none of the lives of the women there are included in this book. Their stories are set aside for another day.
