Understanding Serial Killer Romance

What Is Serial Killer Romance?

Serial killer romance is a dark romance subgenre where one or both romantic leads are serial killers. Unlike thriller novels where killers are antagonists, these books present killers as romantic heroes or anti-heroes worthy of love and redemption (though not all find redemption).

• Serial killer as protagonist, not villain
• Romantic relationship develops despite or because of killer’s nature
• Focus on psychology and motivation behind killing
• Often includes dark themes like obsession, possession, and moral ambiguity
• Blends romance tropes with horror and thriller elements

Not to be confused with:

• Thrillers about catching serial killers
• Horror novels featuring killers as villains
• True crime books about real killers
• Romantic suspense where heroes fight killers
