Number the Stars by Lois
It tells the story of a Danish girl growing up in World War II with her best friend, Ellen, who happens to be Jewish. When she learns about the horrors that the Nazis are imposing on the Jewish people, she and her family stop at nothing to protect Ellen and countless other Jews. Lois' novel is a powerful reminder that cultural and religious differences are no divide between true friends.
The Little Prince by Antoine
It is the story of a little boy who falls to Earth from an Asteroid (小行星)after visiting several other asteroids to try to understand mankind. In his travels he meets a series of strange and delightful characters and an untamed fox. The Little Prince is a heartwarming tale of the power of friendship and trust.
Charlotte's Web by E. B. White
Who doesn't love a novel about talking animals? It opens the door to imagination, asking us to imagine what a world where animals could talk would be like. On a more serious note, it challenges us to ask ourselves how we'd treat animals if they could talk. If they could tell us their joys and their fears, would mankind treat them more humanely?
To Kill a Mockingbird by Harper Lee
The story centers on Jean Louise Finch, an unusually intelligent girl who ages from six to nine years old during the novel. Her father, Atticus Finch, a well-known and respected lawyer, defends Tom Robinson, an African American who is falsely accused of killing a young white woman. It is both a young girl's coming-of-age story and a darker drama about the roots and consequences of racism and prejudice in society.
