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.
Garnet could be a great addition. Her wisdom and calm nature could provide some contrast to Steven and Amethyst's more impulsive personalities. She could also offer some valuable advice to them during their adventures.
Self - discovery is another common theme. Amethyst may learn more about her powers, her past, or her true self in the fanfic stories. This can involve her coming to terms with her flaws and learning to grow as a character.
I'm not sure specifically as there could be many different 'amethyst graphic novels'. It might be about a character named Amethyst, perhaps her adventures, relationships, or some sort of fantasy world she inhabits.
You can use 'ring ring ring ring' as a signal for something exciting in the story. For example, in a story about a wizard's apprentice, the 'ring ring ring ring' could be the sound of a magical alarm that warns of a dragon approaching.
One bedtime story could be about a magical bell that goes 'ring ring ring ring'. The bell is in an enchanted forest and every time it rings, it wakes up the little fairies who then start their day of spreading magic and kindness in the forest.
There's a fanfic called 'Amethyst and Peridot's Team - Up'. In this one, they work together to solve a mystery in their world. It shows their unique personalities very well. Amethyst is all about action and Peridot is the brainy one in the team. It's a really fun read.
Another theme is the power of love to transform. In many amethyst love fanfictions, her love for someone changes her perspective and makes her a better version of herself. It could be that she becomes more empathetic or more confident. For instance, in 'Amethyst's Redemption in Love', she overcomes her past insecurities because of the love she experiences.
