Well, 'Romeo and Juliet' is a very well - known one. They had to hide their love as their families hated each other. It ended tragically. Also, 'Abelard and Heloise' is a famous forbidden love story. Abelard was a philosopher and Heloise was his student. Their relationship was considered improper in the society of that time. The love between them led to Abelard's castration and their separation. And in 'Wuthering Heights', Heathcliff and Catherine had a complex and forbidden love. Heathcliff was of a lower social class, and their love was opposed by many around them.
The story of 'Romeo and Juliet' is a prime example. The two families' feud made their love forbidden. Romeo, a Montague, and Juliet, a Capulet, had to meet in secret. Their love was so strong that they were willing to go against their families. 'Anna Karenina' by Tolstoy also has elements of forbidden love. Anna was married, but she fell in love with Vronsky. This love was against the social norms of her time. In the end, it led to her downfall. Then there's the story of 'Orpheus and Eurydice'. Orpheus was not allowed to look back at Eurydice when leading her out of the underworld, but he did, losing her forever, which was a kind of forbidden action in the context of the myth.
One classic is 'Romeo and Juliet' in a way. Although not directly about interracial love in the modern sense, the Montagues and Capulets were feuding families which can be seen as a form of 'forbidden' love. Another is 'The Great Gatsby'. Gatsby's love for Daisy was somewhat 'forbidden' due to their different social classes which can be analogized to an interracial relationship in terms of the barriers they faced. Also, in 'Othello', the relationship between Othello, a Moor, and Desdemona was considered controversial at the time as they came from different racial and cultural backgrounds.
Typically, they involve love that goes against social norms. For example, in 'Romeo and Juliet', the family feud is a social norm that forbids their love. This creates a strong sense of conflict that drives the plot forward.
In 'Romeo and Juliet', the main characters are Romeo Montague and Juliet Capulet. In 'Lancelot and Guinevere', it's Lancelot, the knight, and Guinevere, the queen. For 'Tristan and Isolde', Tristan the knight and Isolde the betrothed woman are the main characters.
One classic example is 'Twilight'. In it, Bella and Edward have a forbidden love. Edward is a vampire, and their relationship goes against the natural order in the vampire world which forbids vampires from getting too close to humans. Their love is filled with challenges like the threat from other vampires and the fact that Edward has to constantly resist his vampire instincts.
Another is 'Wuthering Heights' by Emily Bronte. The love between Heathcliff and Catherine Earnshaw is complex and forbidden. Heathcliff, an orphan, falls in love with Catherine, but their different social statuses and the cruelty of society at that time make their love full of obstacles. It's a story full of passion, revenge and unrequited love.
Well, there's 'Romeo and Juliet'. They couldn't be together because of their families' hatred for each other. It's a classic example of how society's divisions can create forbidden love. Then there's the story of 'Orpheus and Eurydice'. Orpheus goes to the underworld to bring back his dead wife Eurydice. The gods allow it on the condition that he doesn't look back at her until they are out of the underworld. But he fails, and they are separated forever. It shows how fate can be cruel to lovers. And don't forget about 'Paris and Helen' from Greek mythology. Paris, a Trojan prince, abducted Helen, the most beautiful woman in the world who was already married to a Greek king. This led to the Trojan War.
One popular type is the vampire - human forbidden love in fanfiction. For example, in some Twilight - inspired fanfics, there are different takes on Bella and Edward's relationship. Another could be the forbidden love between characters from different social classes, like a servant and a noble in a period - drama - based fanfiction.
One characteristic is that they tend to have a high emotional intensity. The lovers are often deeply in love in the face of great odds. For instance, in the story of Heloise and Abelard.

Their story also shows that forbidden love can have long - lasting consequences, as their relationship had a great impact on their lives and on the way their story was remembered in history.

In this book, it may tell the stories of those who are in such relationships and are unashamed of their love, despite the cultural taboos.
One example could be a story where two people from different social classes are married. One of them falls in love with someone from their own past, a relationship that was once broken due to family or social pressure. But now, in the context of their marriage, that old love resurfaces as a forbidden feeling.
