Set in Constantinople in the fifteenth century, in a small town in present-day Idaho, and on an interstellar ship decades from now, Anthony Doerr's gorgeous third novel is a triumph story about children on the cusp of adulthood in worlds in peril, who find resilience, hope--and a book. In Cloud Cuckoo Land, Doerr has created a magnificent tapestry of times and places that reflects our vast interconnectedness--with other species, with each other, with those who lived before us, and with those who will be here after we're gone. Thirteen-year-old Anna, an orphan, lives inside the formidable walls of Constantinople in a house of women who make their living embroidering the robes of priests. Restless, insatiably curious, Anna learns to read, and in this ancient city, famous for its libraries, she finds a book, the story of Aethon, who longs to be turned into a bird so that he can fly to a Utopian paradise in the sky. This she reads to her ailing sister as the walls of the only place she has known are bombarded in the great siege of Constantinople. Outside the walls is Omeir, a village boy, miles from home, conscripted with his beloved oxen into the invading army. His path and Anna's will cross.
