The Firefly Collector is a police thriller filled with mystery and unexpected twists.
The story follows Gabriel, a failed writer suffering from a terminal illness, who discovers the brutal murder of his closest friend, a priest, inside a church. The crime scene reveals symbols linked to an ancient cult they both believed to be long extinct.
When a series of crimes begins to follow the same pattern, the investigation falls into the hands of Detective Sara, Gabriel's daughter. As the evidence starts to point toward her own father, Sara finds herself torn between institutional pressure and her conviction that he is merely a pawn in an ancient, ruthless conspiracy carefully concealed by powerful and influential figures.
