I'm not sure specifically what 'keri arthur fantastic fiction' is about without more context. It could be a genre of fiction created by Keri Arthur, perhaps involving elements like magic, adventure, and unique characters.
The unique blend of genres. They often mix romance, mystery, and the supernatural. For example, in her books, a love story might unfold while the characters are also solving a mystery involving vampires or werewolves.
Given that it's 'fantastic fiction', it might target a wide range of audiences. Fantasy lovers, of course, but also those who are into stories that have a touch of mystery and adventure.

Since I haven't read this novel myself, I can only make some educated guesses. It could be that the 'city of light' is a sort of utopian or dystopian setting. The outcasts might be those who don't fit into the norms of this city. The story could revolve around their adventures, their attempts to change the status quo, or perhaps their discovery of some hidden secrets within the city. It might also deal with the power dynamics between the different groups in the city, with the outcasts being at the bottom of the hierarchy initially and then trying to rise up. There could be elements of mystery, action, and character - driven drama as the outcasts navigate their lives in this unique city.
Since I haven't read the novel, it's difficult to say for sure. However, it's likely that the main characters are the outcasts in the city of light. Maybe there's a character who is the spokesperson for the outcasts, someone with a strong will and a desire to make a change for their group. There could also be characters from the 'normal' part of the city who interact with the outcasts in significant ways.
I'm not aware of any existing erotic stories specifically about Keri Russell. She is known more for her acting work in mainstream movies and TV shows rather than being associated with such inappropriate content.
