You can start by looking in your local bookstores. They might have it in their inventory, especially if they have a section dedicated to supernatural or werewolf - themed books. Another option is to search for it on online book retailers like Barnes & Noble's website or Amazon.
I'm not sure about a specific werewolf novel titled 'She's Mine'. However, there are many popular werewolf novels in general. You could try searching on e - reading platforms like Amazon Kindle or Goodreads. They often have user reviews and recommendations which can help you find similar werewolf novels if this one is hard to locate.
Since the title is 'She's Mine novel', we can assume there is a protagonist, probably a male, who is deeply involved with the 'she' in the story. There might be a group of friends or family members around them. Maybe there's an antagonist, like another person who also has feelings for the girl and tries to come between the main couple. Without reading the novel, it's hard to say exactly who all the main characters are, but these are some common types of characters we might find.
In the 'She's Mine novel', perhaps it tells the story of a relationship. It might start with the main character falling in love with the girl and then facing obstacles like family disapproval, or the interference of other people who also have an interest in the girl. The story could be about how he overcomes these and makes her truly his, showing themes of love, loyalty, and determination.
Well, in Twilight fanfiction, 'She's Mine' might revolve around a power struggle. There could be different factions vying for a particular female character. If it's set in the context of the vampire clans, perhaps one clan leader sees a female as key to their plans and says 'She's Mine' to assert dominance and control over the situation.
I'm not sure specifically as there are countless Twilight fanfictions. But it could be Bella and Edward, where Edward is more possessive than in the original story and really emphasizes that Bella is his. Or it could be a new character and Jacob, where Jacob has found a new love interest and is very protective of her.
Well, obviously there's the female character who is 'back' and her new mate. But without reading the novel, it's hard to say if there are other important characters. There could be an alpha in the werewolf pack who has a say in their relationship.
Another theme is isolation. Since she is hiding her werewolf identity, she often feels alone. In 'Shiver', the female character feels that she is different from others and this sense of being an outsider due to her secret is a strong theme. It's not easy for her to form close relationships as she fears her secret will be exposed.
One such interesting novel could be 'Shiver' by Maggie Stiefvater. In this book, the female character has some secrets related to her 'wolf - like' nature which she tries to hide. It's a great read with a beautiful blend of romance and the supernatural.
