  "description": "Jack Londons 1903 erschienener Abenteuerroman, der die Zeit des Goldrauschs beschreibt, gilt als eines seiner besten Werke. Es ist die Geschichte von Buck, einer Mischung aus Bernhardiner und Schlittenhund, der menschlicher Brutalität und Gewalt ausgesetzt ist und erst durch den Goldgräber Jack Thornton Güte und Freundlichkeit kennenlernt: ein eindrucksvolles Plädoyer für Menschlichkeit und Nächstenliebe und ein spannendes Abenteuer, das bis zur letzten Seite fesselt.",
