Set against the construction of the Eiffel Tower, this novel charts the relationship between a young Scottish widow and a French engineer who, despite constraints of class and wealth, fall in love. In February 1887, Caitriona Wallace and ?%mile Nouguier meet in a hot air balloon, floating high above Paris, France--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. ?%mile is expected to take on the bourgeois stability of his family's business and choose a suitable wife. As the Eiffel Tower rises, a marvel of steel and air and light, the subject of extreme controversy and a symbol of the future, Cait and ?%mile must decide what their love is worth. Seamlessly weaving historical detail and vivid invention, Beatrice Colin evokes the revolutionary time in which Cait and ?%mile 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.
