Constantinople, 1453: Anna lives in a convent where women toil all day embroidering the robes of priests. She learns the story of Aethon, who longs to be turned into a bird so that he can fly to the paradise of Cloud Cuckoo Land, a better world, and reads it to her sister as the walls of Constantinople are bombarded by armies of Saracens. Lakeport, Idaho, 2020: Seymour, an activist bent on saving the earth, sits in the public library with two homemade bombs in pressure cookers. Upstairs, eighty-five-year old Zeno, a former prisoner-of-war and an amateur translator, rehearses five children in a play adaptation of Aethon's adventures. The future: On an interstellar ark called The Argos, Konstance, alone in a vault with access to all the information in the world, knows Aethon's story through her father, who has sequestered her to protect her. All are dreamers, misfits on the cusp of adulthood in a world the grown-ups have broken. -- Adapted from publisher information.
