Paul Atreides 'sister was Alia.

Alia Atreides was the main character in Frank Herbert's novel Dune. She was Paul Atreides 'sister, born in a valley in the Arrakian desert. Her mother, Lady Jessica, had consumed the Water of Life during her pregnancy, causing her to be born as a Bene Gesserit. In the story, Alia helped her brother Paul and became the regent queen to manage the empire. She played an important role in the story, especially in Dune 2. As for her ending or subsequent plot, there was no specific content mentioned in the search results.

I'm not entirely sure without reading it specifically, but likely there are members of the House Atreides family as main characters.

Duke Leto Atreides, the leader of the Atreides family in Dune, was a benevolent ruler. The Atreides were from Caladin, and Emperor Padisha had given them control of Arrakis, replacing the Harkonnens, who had been their nemesis. Duke Leto worked hard to protect his family from harm, and his son Paul began to realize that he had a great mission on Arrakis. Lady Jessica was Duke Reto's beloved concubine, and she was also Paul's mother. As a member of the Bene Gesserit Sisterhood, Lady Jessica trained her mind through mental manipulation and spices, and gained superhuman strength. Their leader, Mother Mohiam, was obsessed with the breeding program and wanted to create an all-rounded member of the Bene Gesserit named " Kwisatz Hadrak."

Alia's father was Duke Leto.

Power is a common theme. Feyd Rautha is often depicted as vying for more power within the Harkonnen family or in the larger Dune universe. Another theme is loyalty, whether it's his loyalty to his family or the lack thereof as he might plot against them. Betrayal also shows up a lot, as he's a character known for his devious nature in the original Dune story.

The planet no longer belonged to the Atreides. In the story of Dune, the home planet of the Atreides, Caradhan, was granted control of Arrakis by Emperor Padisha, and was temporarily managed by Count Hasmir Fenlin. Thus, the planet no longer belonged to House Atreides.

The 'House Atreides' novel is mainly about the noble House Atreides. It delves into their politics, power struggles, and the complex relationships within the house. It also likely explores their place in the greater galactic or fictional universe it's set in.
