Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

Selbst der Tod hat ein Herz ... Molching bei München. Hans und Rosa Hubermann nehmen die kleine Liesel Meminger bei sich auf – für eine bescheidene Beihilfe, die ihnen die ersten Kriegsjahre kaum erträglicher macht. Für Liesel jedoch bricht eine Zeit voller Hoffnung, voll schieren Glücks an – in dem Augenblick, als sie zu stehlen beginnt. Anfangs ist es nur ein Buch, das im Schnee liegen geblieben ist. Dann eines, das sie aus dem Feuer rettet. Dann Äpfel, Kartoffeln und Zwiebeln. Das Herz von Rudi. Die Herzen von Hans und Rosa Hubermann. Das Herz von Max. Und das des Todes. Denn selbst der Tod hat ein Herz. „Die Bücherdiebin“ ist eine Liebesgeschichte, eine Hommage an Bücher und Worte und eine Erinnerung an die Macht der Sprache, die im Roman von Markus Zusak viele Facetten zeigt: den lakonisch-distanzierten Ton des Erzählers, Poesie und Zuversicht – und die reduzierte Sprache der Nazipropaganda.
