After discovering their death-based powers, Charlie and Sam Ford have to master their life-taking and life-giving abilities to manage their flock of ghosts. They move to NYC and ally with the DaRosa twins of the House of Scorpion to learn how to harness their ghosts' power to protect themselves, stalk rival Houses, or even control the weather. But when the DaRosas?s ghosts start disappearing without explanation, it could upset the balance of power between all the Houses forever. When the House Council casts suspicion on Charlie?s family, it?s up to Charlie and Sam to figure out what?s happening to their ghosts before other Houses?s ghosts start disappearing too. Their investigation leads them to the Osman twins, who honor a tradition more ancient and secret than any modern House has ever known. With new knowledge of what their powers can do, and a new perspective on what their powers are truly meant for, Charlie and Sam will have to decide if they are willing to fight the most powerful Houses to do the right thing for the dead.
