In Steven Universe fanfiction, the relationship between Steven and Amethyst can be really interesting. They are both very different characters. Steven is kind - hearted and has a strong sense of justice, while Amethyst is more of a free - spirited and somewhat rebellious character. In some fanfictions, their relationship might develop into a deep friendship where they support each other through different challenges. For example, Steven could help Amethyst come to terms with her insecurities about being a 'lesser' gem compared to the others.
Adventure is also a common theme. They go on different quests or face various threats together. This could be something like exploring an ancient gem ruin on Earth or fighting off a new enemy. The theme of acceptance is important too. Accepting each other's flaws and differences. Amethyst accepting Steven's sometimes naive view of the world, and Steven accepting Amethyst's wilder side.
There might be such a fanfic. The 'Steven Universe' fandom is quite large and creative. However, it's also possible that it doesn't exist. You could try searching on popular fanfic websites like Archive of Our Own or FanFiction.net to see if there's a story with this concept.
One possible theme could be discovery. As I said before, if the lemon is some sort of new or magical object, the characters are on a journey of discovery about it. Another theme could be acceptance. If 'lemon' is a new character or concept, the other characters have to learn to accept it. For example, Amethyst might be more open - minded while others like Garnet or Pearl might be more skeptical at first.
A 'Steven Universe Amethyst Pregnant' fanfic could be a story that delves into the origin of the pregnancy. Is it some sort of magical or scientific anomaly? How does Amethyst feel about becoming a mother? She has always been the more carefree and fun - loving gem among the Crystal Gems. This new situation could force her to grow up in a way. It could also touch on the theme of family and what it means to create a new life within the context of the unique world of 'Steven Universe', exploring how the different species and cultures in the show interact with this unexpected event.
It could be about a unique adventure. Maybe Amethyst discovers a lemon - shaped magical object and she and Steven go on a journey to figure out its power. Since Amethyst is known for her wild and carefree nature, she might get into some comical situations while exploring the mystery of this lemon - related item with Steven.
Perhaps some remnants of Homeworld's military that still hold a grudge against the Crystal Gems. They might think that by kidnapping Amethyst, they can force the Gems to stop their activities on Earth or give up some valuable information.
Well, in such a fanfiction, the other characters like Steven and the Crystal Gems would likely go on a rescue mission. They'd use their powers to track her down. Steven might use his shield to protect them during the search, and Pearl could use her spear skills. Garnet would probably be leading the way with her future vision to find Amethyst as quickly as possible.
I don't know who the author of 'Amethyst Novel' is. There are so many novels out there, and without more context, it's difficult to determine the author.
Since I don't have more information on 'Amethyst Novel', it could be a fantasy novel where amethyst has some magical properties. Maybe the main character has an amethyst amulet that gives them special powers. It could also be a love story set in a place where amethyst is mined.
