S.P. Luna

In winter-dark Brooklyn, Renley House keeps its secrets warm. Pietra learned young that a locked door could mean shelter or prison, depending on who held the key. After surviving a Bureau raid, Blue Ash, and the destruction of the hidden house that once kept her safe, Pietra carries her fire south with only one impossible companion beside her: Blaze, a small fire-born cat with the attitude of a king.
Years later, Pietra belongs to Renley House. The old Brooklyn brownstone is full of locked doors, hidden cameras, dangerous men, and Lawrence Renley, a ruthless crime lord trying to inherit his father's empire without becoming his father in the process. Lawrence gives Pietra shelter. He gives her work. He gives her a place where her fire is useful, feared, and protected. But protection can look a lot like control when someone else is holding the key.
When the Thermal Regulation Bureau and the Red Saints begin moving through Brooklyn, Pietra is forced to decide what Renley House really is: another cage, or the first place dangerous enough to become home. Bloodfire at Renley House is an atmospheric urban fantasy novella featuring a powerful pyromancer heroine, a morally gray crime lord, a magical firecat companion, secret government agencies, winter Brooklyn atmosphere, found family tension, and slow-burn romantic undertones.
