Love and Capital is a huge, often gripping book. It gives an entertaining and balanced portrait of Marx, Engels, their colorful milieu of exiles, freaks and revolutionaries, and the little-known Marx family, dominated by Karl’s political obsession. It also details illicit love affairs, the deaths of children and financial struggles, all based on vast research and narrated with empathetic passion…[It’s] enjoyable…because of the details of family life and family politics that Gabriel offers up – her vivid portrait of a struggling, obsessional bohemian intellectual in the capitals of mid-19th-century Europe.”–Simon Sebag Montefiore, New York Times Book Review
