Which Lois Lowry historical novel won the 1990 Newbery Medal?

The historical novel by Lois Lowry that won the 1990 Newbery Medal was Number the Stars.

Published in 1989, Number the Stars is set in German-occupied Denmark during World War II. It follows ten-year-old Annemarie Johansen, whose Jewish friend Ellen Rosen is sheltered by Annemarie’s family as the Danish Resistance helps Jewish families escape to neutral Sweden. The novel presents frightening events through a child’s perspective while emphasizing courage, friendship, sacrifice, and ordinary people’s resistance to persecution.

Lowry drew on historical accounts, including stories connected to her Danish friend Annelise Platt. The novel is often confused with Lowry’s dystopian book The Giver, which won the 1994 Newbery Medal, or with Gathering Blue, a later companion novel that did not win the medal. A Summer to Die was Lowry’s first published novel, while Anastasia Krupnik belongs to her humorous family series.
