What if books were forbidden, imagination was dangerous, and the truth could change everything? In Building 903, beloved author Lois Lowry returns to the thought-provoking dystopian storytelling that made The Giver a modern classic.

Twins Tessa and Theo live in a society ruled by a powerful leader who promises safety, comfort, and long lives. Although many citizens quietly resent their ruler, few dare to question the world around them. But when Theo mysteriously disappears, Tessa refuses to accept the silence surrounding her brother’s fate.

Then Miriam, their 135-year-old neighbor, gives Tessa a mysterious key that leads to something extraordinary: books. In a world where stories have been suppressed, Tessa discovers that books possess a remarkable power to open portals, inspire imagination, and reveal possibilities beyond the limits of her controlled society.

As Tessa and her parents search for Theo, she begins to understand that imagination may be the greatest threat to those who control her world. To rescue her brother, she must confront the truth about her society and discover the courage to imagine something better.

Exploring censorship, freedom, conformity, and the transformative power of reading, Building 903 is a compelling middle-grade novel for fans of The Giver and readers who love meaningful science fiction and dystopian adventures. A particularly fitting choice for book clubs, classrooms, and conversations about the freedom to read.
