To capture what we cannot keep / Beatrice Colin.

'As the Eiffel Tower rises, a marvel of steel and air and light, the subject of extreme controversy and a symbol of the future, a young Scottish widow and the Tower's engineer fall in love... In February 1887, Caitriona Wallace and Émile Nouguier meet in a hot air balloon, floating high above Paris - a moment of pure possibility. But back on firm ground their vastly different social strata become clear. Cait is a widow who, because of her precarious financial situation, is forced to chaperone two wealthy Scottish charges. Émile is expected to take on the bourgeois stability of his family's business and choose a suitable wife. With these constraints of class and wealth, Cait and Émile must decide what their love is worth... Seamlessly weaving historical detail and vivid invention, Beatrice Colin evokes the revolutionary time in which Cait and Émile live - one of corsets and secret trysts, duels and bohemian independence, strict tradition and Impressionist experimentation. To Capture What We Cannot Keep, stylish, provocative and shimmering, raises probing questions about a woman's place in that world, the overarching reach of class distinctions, and the sacrifices love requires of us all.' -- Back cover.
