GhostBox (Comixology Originals) #4

When Chloe gets a chance to be reunited with her dead sister she grabs it with both hands – and falls into Sabine de Thibhert’s insidious trap. Sabine intends to buy her freedom from the ghostbox with the Estival’s help – and with the ghostbox itself as the price. But there’s one wild card still in play, because the box has a new inhabitant.
