I'm not sure specifically which 'My Own Destiny' novel you are referring to. There could be many novels with this title. It would be helpful to have more context, such as the genre of the novel (e.g. romance, fantasy, etc.) or the time period it was written in.
One way is to search for the book title on popular book - selling websites like Amazon or Barnes & Noble. Usually, the author's name is clearly stated there along with the book details.
First, you need to be well - versed in the Destiny lore. Know the different races, classes, and the overall world - building. Then, come up with an interesting concept. It could be a new adventure for a popular character or a unique take on an existing event in the game.
First, immerse yourself in the Destiny universe. Play the game, read the official lore, and understand the different races, classes, and locations. Then, come up with an original idea. It could be a new adventure for a Guardian, or a different take on an existing event. For example, what if a Guardian had to team up with a Fallen instead of fighting them? Start writing and don't worry too much about making it perfect at first.
Just start with what interests you most. If a particular area or character catches your eye, start with the quests related to them. That way, you'll be more engaged from the get - go.
To start writing X - Men Destiny fanfiction, think about the themes that interest you in the X - Men universe. Is it the struggle for mutant rights? The complex relationships between the characters? Once you've identified the theme, build your plot around it. You can start with a simple outline, like a beginning, middle, and end. For the beginning, introduce your setting and characters. In the middle, develop the conflict, and in the end, resolve it. Also, don't be afraid to add your own unique twists. Maybe a mutant has a power that no one expected, or there's a secret alliance that changes everything. And remember to write in a style that suits the X - Men Destiny tone, which is often a mix of action, drama, and a bit of sci - fi.
