It is 1943 in Copenhagen, and Annemarie’s life is simple. She enjoys playing with her closest friend, Ellen, and has the same troubles as any other ten-year-old girl. Then one day Nazi soldiers stop and question her and Ellen on the street. Annemarie notices that families are disappearing and suddenly, her dear friend Ellen, a Jew, is caught in the midst of the trouble. Newbery Award-winning author Lois Lowry’s Number the Stars (Houghton Mifflin Harcourt, $17.99), has been reissued in a gorgeous 25th-anniversary edition. Its introduction of the Holocaust to young readers in an appropriate, yet heart-wrenching, way is as relevant today as it was when it was first printed.  Ages 9-12. ARW
