A cool concept could be an alternate universe where humans and aliens have been interbreeding for generations. The story could focus on a young character who is part - alien and part - human and their journey to discover their true identity and find their perfect alien mate among different alien races.
Well, often there's a focus on the differences between the human and alien species. For example, in terms of physical appearance like different skin colors or body structures. There's also the cultural gap. Aliens may have different mating rituals, social hierarchies, and values. In these books, the romance usually builds as the characters learn to understand and accept these differences.
The novelty. It combines two very different concepts - aliens and romance. People are curious about the unknown, and aliens represent that. When combined with the universal theme of love, it creates a unique reading experience.
One popular one could be 'Ice Planet Barbarians' series. It involves human females being abducted to an alien planet and having romantic relationships with the alien mates there.
Give them distinct physical features. For example, an alien mate could have multiple eyes or tentacles. These unique features can influence their behavior and how they interact with the human or other alien characters.
One great example is 'Ice Planet Barbarians' by Ruby Dixon. It features a human woman stranded on an alien planet and her relationship with an alien male. The story is full of adventure, cultural differences, and of course, romance.
It could be Hermione. In some alternate interpretations, there could be a situation where Hermione, while trying out a new and powerful magic, accidentally hurts Harry. Their friendship is put to the test as Harry has to deal with the pain and Hermione has to come to terms with what she's done.
😋I recommend the following novel to you: " Super Alien ". The protagonist of this sci-fi novel, Jiang Lie, has been transformed into an Alien, but he can retain his intelligence and the ability to devour and assimilate the genes of any living creature. In the process of exploring the universe, he was faced with the choice between death and evolution. This novel is similar to the Alien King and the Apocalypse Alien Dominator. I believe you will like it. I hope you like my recommendation.😗
Maybe it's Ron. Suppose Ron gets jealous of Harry's fame and power and, in a moment of weakness and envy, decides to abandon Harry to die. This would create a lot of drama as Ron and Harry have been friends for a long time, and such a betrayal would be a huge shock to the story's readers.
