At twenty years old, you’ve never wanted a different life. Being Bobby Singer’s oldest daughter meant growing up with a shotgun before a driver’s license, learning to stitch knife wounds before hemming a dress, and accepting that monsters were as real as sunrise. Your seventeen-year-old half sister, Addy, is your opposite in every way. Where you’re in the field beside Bobby, she’s surrounded by ancient lore books at Singer Salvage, piecing together legends, translating dead languages, and finding the answers that keep you alive. It’s a system that’s worked for years—you and Bobby handle the monsters, Addy handles the research.
