It's been raining for a long time now, for so long that the lands have reshaped themselves and the cities have retreated to higher storeys. Old places have been lost. Arcane rituals and religions have crept back into practice. Sisters Isla, Irene and Agnes have not spoken in some time when their estranged father dies. A famous architect revered for making the new world navigable, he had long cut himself off from public life. They find themselves uncertain of how to grieve his passing when everything around them seems to be ending anyway. As the sisters come together to clear the grand glass house that is the pinnacle of his legacy, they begin to sense that the magnetic influence of their father lives on through it. Soon it becomes clear that others have also taken an interest in both his estate and in them, and that perhaps their inheritance may not be theirs alone.
