What are monster romance books all about?

Monster romance books are a subgenre of romance fiction that involve a romantic relationship between a human and a monstrous being. These stories may be set in the present day or in the past, and may include elements of fantasy, science fiction, or horror.

The stories may revolve around themes such as acceptance, tolerance, and the dangers of fear and prejudice. Monster romance books often focus on the physical differences between the protagonists and feature tropes such as height differences, strength differences and physical incompatibilities.

Monster romances tend to emphasize the monster’s ability to commit acts of violence but also to be a protector.
