Magic and the supernatural are often themes as well. Stolas has powerful magic abilities, and fanfics play with how he uses them, discovers new powers, or how his magic affects his relationships. Some fanfics also explore the origin of his magic and how it ties to his family's history.
There's 'Stolas and His Daughter'. This fanfic focuses on Stolas' relationship with his daughter. It shows his more tender side and how he tries to be a good father in the complex world he lives in. It's a heartwarming read.
Another theme is the power dynamic between them. Stolas is a powerful demon with a high social standing, while Blitz is more of an underdog in a way. Fanfictions may play with this power dynamic, sometimes having Blitz gain power or influence in the relationship, or Stolas learning to respect Blitz's agency more. Also, there are often themes of redemption and self - discovery for both characters within the context of their relationship in these fanfictions. They might grow and change as a result of their connection to each other.
A plotline might involve them going on adventures together outside of their usual work - related tasks. They could discover new aspects of each other's personalities and grow closer as a result. Also, there could be a plotline where they face opposition from other characters in the Helluva Boss universe who don't approve of their relationship.
The contrast between their characters. Stolas is refined and powerful, while Blitz is rough around the edges and scrappy. This creates a dynamic that fans find interesting to explore in fanfiction.
You can try websites like Archive of Our Own (AO3). It has a large collection of fanfictions across various fandoms, and there are likely many Stolas x Blitz fanfictions there. Just use the search function on the site.

I'm not sure specifically as there could be many novels with that title. It might be about a mother - perhaps her relationship with her family, her struggles, or her achievements.
Sorry, I have no idea about the author of this 'Mother Mother a novel'. There are countless novels being published, and this one might be a bit of a mystery in terms of its authorship. You could try asking in a local book club or on a literature - focused forum to see if anyone knows.
