Siren fiction typically focuses on the idea of sirens. Sirens are often seen in ancient Greek mythology. In siren fiction, we can expect to see themes of temptation and danger. For example, a hero might be lured by the siren's song and have to fight against the urge to follow it. It can also explore the nature of the sirens themselves, whether they are truly evil or just acting according to their nature.
A siren novel is likely a type of novel that involves the concept of sirens. Sirens are often mythological creatures, half - woman and half - fish in many stories. So a siren novel might be a story that revolves around these alluring and mysterious beings, perhaps with themes of temptation, the sea, and adventure.
One common theme is identity. Sirens often have to figure out who they are, especially when they are different from others. For example, in 'To Kill a Kingdom', the siren character has to redefine herself.
