Purely Fictional Books VS Based on Real-Life Cases
Fictional Serial Killer Romance Books |
Inspired by Real-Life Cases |
| These stories are completely made up, with killers that are often mysterious, charming, or even have a twisted moral code (like only killing bad people). | These take inspiration from actual serial killers, either by using real details or loosely basing the characters on them. |
| They focus more on dark fantasy and intense romance rather than real-world crime. | They tend to feel more realistic and unsettling because they’re tied to real crimes. Some explore the psychological impact of loving someone dangerous, while others just borrow details for extra shock value. |
| The goal is to entertain, thrill, and explore dangerous attractions in a way that feels larger than life. | These books can be more controversial, especially when they blur the line between fact and fiction. |
