The Brookes are gathering in their eighteenth-century ancestral home - twenty bedrooms of carved Sussex sandstone - to bury Philip, the head of the family – the blinding sun around which they have all orbited for as long as they can remember.

Frannie, inheritor of a thousand acres of English countryside, has dreams of rewilding and returning the estate to nature: a last line of defence against the coming climate catastrophe. Milo envisages a treetop haven for the super-rich where under the influence of psychedelic drugs a new ruling class will be reborn. Each believes their father has given them his blessing and are set on a collision course with the other.

Isa has long suspected that her father thought only of himself, and only hopes to seek out her childhood love, who still lives on the estate, to discover whether it is her feelings for him that are creating the fault lines in her marriage.

And then there is Clara, who arrives in their midst from America, shrouded in secrets and bearing a truth that will fracture all the dreams on which they’ve built their lives.
