There's a great fanfic called 'Honor Harrington in Pern'. It brings the Honorverse into the world of Pern. The contrast between the high - tech naval battles of Honor's world and the dragon - riding society of Pern makes for a really exciting read. Also, 'Honor's Journey through Middle - earth' is a fan - favorite. It shows Honor's journey in the Lord of the Rings universe, and how she interacts with the different races there.
One interesting concept could be the merging of Honor Harrington's universe with another well - known science fiction universe like Star Trek. Imagine Honor's naval tactics being applied in the context of the Federation's exploration and defense missions. Another concept might be a crossover with the Battlestar Galactica universe, where the Honorverse's ship - building technology could interact with the Cylons' advanced robotics.
One great piece of 'honor harrington fan fiction' is 'A Different Path' which explores an alternate timeline for Honor. It's really interesting as it delves deep into character relationships in a new setting.
Another good one is 'For Honor in the Lord of the Rings Universe'. Here, the For Honor characters are transported to Middle - earth. They face off against orcs and other creatures. The fanfiction delves into how their honor - based combat system would work in a world full of magic and ancient races. It has some really intense battle scenes and great character development as they learn about the new world.
There's also 'Steve's Unlikely Ally'. In this fanfiction, a female character is introduced who at first seems to be at odds with Steve. But as the story progresses, they find out they have a lot in common and end up working together to solve the mysteries in Hawkins. It's full of action and some really sweet moments between the two characters.
The most recent Honor Harrington novel that I'm aware of is 'Mission of Honor'. It continues the epic space opera saga. In this novel, we see more of Honor's adventures, her leadership skills being put to the test in the complex and dangerous political and military situations in the Honorverse. There are new characters introduced, and the relationships between the existing characters also evolve, making for an engaging read for fans of the series.
I'm not sure of specific titles off - hand, but you can start by looking on popular fanfiction websites. Search for ones with high ratings and a lot of reviews. Usually, those are the better - quality ones.
There are also 'zombie crossover fanfiction' that combines zombies with a fantasy world like Middle - earth from 'The Lord of the Rings'. Picture hobbits and elves trying to survive a zombie outbreak. It adds a whole new layer of drama and adventure to the familiar fantasy setting. Usually, the writers play with the different abilities and cultures in Middle - earth to create unique survival strategies against the zombies.
One popular ufo crossover fanfiction is 'UFOs and the Superheroes'. In this story, the appearance of UFOs disrupts the world of superheroes, creating a whole new set of challenges and alliances. Another interesting one is 'UFO Encounters in the Fantasy Realm' where UFOs enter a magical land, causing a stir among wizards and mythical creatures.
