In this exceptional work of non-fiction — you couldn’t call it just a history book, it’s more than that — the British writer Jane Rogoyska tells the wider story of the hotel, and Paris, and France at war ... She captures the historical moment with a rare combination of urgency and empathy ... This is a scintillatingly good book. I think it will win prizes — not least because it is subtly experimental. It is a group biography. That can make a book labyrinthine, but here it feels right to be a little lost in the maze.
