Surrealistische fantasie, gebaseerd op het Daphnis en Chloë-thema, overgebracht naar Parijs in 1947.
Flaptekst van de Engelse versie Froth on the Daydream vertaald door Stanley Chapman (1967):
L'Ecume des jours is a jazz fueled Science Fiction story that is both romantic and nihilistic! Vian's novel is an assortment of bittersweet romance, absurdity and the frailty of life. Foam of the Daze is a nimble-fingered masterpiece that is both witty and incredibly moving. It is a story of a wealthy young man Colin and the love of his life Chloe, who develops a water lily in her lung.
