In vampire space novels, a recurring theme is the search for a home. Since they are often outcasts or predators, they are constantly looking for a place where they can exist without persecution. Another theme is the evolution of vampires. In the space setting, they may evolve different abilities to cope with the new challenges. Also, the theme of secrecy is present. Vampires usually try to keep their existence a secret from other species in space to avoid being hunted or studied.
Power is also a major theme. In space vampire novels, vampires often have powers that are enhanced or changed in the space environment. They may use these powers to dominate other species or fight for control of space resources. There's also the power struggle between the vampires themselves, especially if there are different factions or clans in the story. And sometimes, the humans in the story try to gain power over the vampires, either through scientific means or by forming alliances with other alien races against them.
Another theme is love and relationships. Just like in any other genre, but with the added layer of the space - related backdrop. The challenges of being in a relationship in a harsh space environment, such as long - distance travel between planets or dealing with different cultural values about relationships, are often explored. For instance, a gay couple might face difficulties when one partner's home planet has very conservative views on same - sex relationships.
The power of faith is a huge theme. The Christian characters in these novels rely on their faith in God to combat the vampiric threats. Also, the idea of the soul is important. Vampires are often seen as soulless or having lost their souls, and this contrasts with the Christian concept of the soul's significance. And there is often a theme of sacrifice, where characters may sacrifice themselves in the name of good and in line with Christian values.
Love is a very common theme. In many supernatural vampire novels, there is often a romantic relationship between a human and a vampire, like in 'Twilight'.
Another theme is redemption. Sometimes, a vampire character may be on a journey to redeem themselves, especially if they have a human side or some sort of moral compass. This can be seen in how they interact with the human characters in the story. It's like they are trying to atone for their vampiric nature in a world full of cowboys and saloons.
Power dynamics is another theme. The vampire character usually has more power, physically and sometimes socially. This can create an interesting dynamic in the relationship as the human or non - vampire character has to navigate this inequality.
One common theme is the clash between the old, often superstitious beliefs of the Byzantine era and the reality of vampirism. For example, how the people in the story react to the presence of vampires in a society that has its own religious and cultural beliefs.
Love is a common theme. Often, there is a love story between a human and a vampire or between two vampires. Another theme is power. Vampires usually have some special powers and there are often power struggles among them.
One common theme is the struggle between different vampire factions. In a school setting, there might be different clans or types of vampires vying for power or control. For example, in 'Vampire Academy', there are the Moroi (good vampires) and the Strigoi (evil vampires), and the students are constantly in the middle of their battles.
Common themes in urban vampire novels include the duality of the vampire's nature. They can be both alluring and terrifying. The exploration of immortality and its implications is another theme. How does one deal with an infinite lifespan? There is also the theme of secrecy and the masquerade. Vampires have to hide their true nature from humans, which creates a lot of tension and drama. And, of course, the theme of the hunt, whether it's for blood or for power in the vampire underworld.
