What are the common themes in Wiens' fantasy novels?

I'm not sure specifically as there's not enough information given. But in general, in a fantasy novel, there could be a young hero or heroine. Maybe a wizard or a warrior type of character who has special abilities and is on a quest.

One common theme is the battle between good and evil. In many fantasy novels, there are clear-cut sides of good characters like heroes and wise wizards, and evil ones such as dark lords and malevolent sorcerers. Another is the journey or quest. The protagonist often embarks on a long and arduous journey to find a magical item, save a kingdom, or fulfill a prophecy.

The search for knowledge and power. Alchemists in these novels are usually in pursuit of the ultimate knowledge of alchemy which they believe will give them great power. This is seen in many such novels where characters risk everything to unlock the secrets of alchemy.

One common theme is survival. Characters often have to fight for their lives in a world decimated by plague, like finding food, shelter, and avoiding the infected. For example, in many such novels, they form groups or communities to increase their chances of survival.

One common theme is power. Witches often have to deal with the power they possess, whether it's controlling it or using it for good or bad. Another theme is isolation. In many novels, witches are seen as different from the normal people, so they are often isolated. And there's also the theme of magic itself, like exploring different types of magic that witches can do.

Fantasy elements often play a role. This could be in the form of magical powers or a special world. In 'Citrus', the intense relationship between the step - sisters is set against a backdrop that has some elements of the extraordinary. Also, friendship is sometimes a theme that blends with love. The girls start as friends or classmates and then develop deeper feelings, like in 'Adachi and Shimamura' where their friendship slowly morphs into something more.

One common theme is self - discovery. Emma often has to learn about her own abilities and identity in these fantasy novels. For example, she might find out she has some special power she didn't know before.

Another common theme is the exploration of a different world or magic system. This serves as a backdrop for the relationship to develop. The unique settings, like a world where magic is based on emotions or a floating island civilization, add depth and intrigue to the story while also allowing the relationship between the female characters to be explored in a new and exciting context.

One major theme is morality. Fantasy assassin novels often explore the gray area between right and wrong. Is it okay to kill for a noble cause? Are assassins just tools or do they have their own agency? Another theme is loyalty. Assassins may have to choose between loyalty to their masters, their friends, or their own beliefs. Also, the theme of identity is common. Assassins may have to hide their true selves, or they may be searching for their true identity among the lies and disguises.

Love and lust are common themes. In sexy fantasy novels, characters often experience intense romantic and sexual attractions. For example, in 'Fifty Shades of Grey' - though it's more on the borderline of pure fantasy - the relationship between the two main characters is centered around a strong sexual attraction.
