I'm drawing a blank on 'Mafia Puppet' by a Jessica. I've combed through my memory and the usual databases, and I can't seem to find a published novel with that exact title and author combination. Sometimes titles get translated differently, or an author might use a pseudonym, but this one doesn't ring any bells for me. It's possible it's a more obscure indie title or a story serialized on a platform I haven't frequented.
If the core of the query is about a mafia-themed story with a 'puppet' dynamic, that's a trope I'm definitely familiar with. Often, it involves a character—usually someone initially outside the criminal world—being manipulated or coerced into acting for the organization, like a puppet on strings. The tension usually comes from their struggle between survival and autonomy, the fear of their handlers, and the moral compromises they're forced to make. The plot might follow their journey from a pawn to someone who learns to play the game themselves, or it could be a tragic arc about their loss of self.
Without the specific book, I'd suggest checking platforms like Amazon or Goodreads with a few different keyword variations, or maybe the story is known under a slightly different title. If it's a web novel, places like Wattpad or Royal Road could be worth a look. The 'mafia puppet' concept itself is a strong hook, promising a mix of suspense, power dynamics, and internal conflict. If you do find it, the execution of that central relationship will likely be what makes or breaks the story.
