The Ikigai Chronicles: The Architect's Daughter. 1, #2

He built cities. He built a second planet. He built the legal architecture for a new kind of civilisation. What he couldn't build - what no architecture could produce - was the particular weight of a four-year-old handing you her plant and saying: you can carry it. It needs more light where you are. The Architect's Daughter is the bridge between the world Nigatu Yomama made and the world his daughter will inherit.
It is the story of what happens to a man who has been invisible for thirty years when he finally steps into a café and lets someone sit across from him. It is the story of Amara - found in a courtyard in Addis Ababa, watching ants, asking the most important questions - who grows from a child who counts leaves to a woman who rewrites the legal architecture of a planet before she is twenty-five. It is the story of the founding documents.
Of a diagnosis that arrives gently and is received with the words: we have work to do. Good work. The kind worth doing. Of Ren, learning - for the first time in forty years - what it means to attend to something small and alive and entirely dependent. Of a friendship between a Japanese orbital mechanics professor and a quiet man from Yokohama that begins when she sits down at his table without being invited.
And it is the story of an ending that is also, unmistakably, a beginning.
