In a world of perennial fire and growing extinctions, Anna's aged mother is dying - if her three children would just allow it. Condemned to living by their pity, she increasingly escapes through her hospital window into visions of horror and delight. When Anna's finger vanishes and a few months later her knee disappears, Anna too feels the pull of the window ... This is Booker Prize-winning novelist Richard Flanagan at his most moving-and astonishing-best.
