And sometime in the future, Konstance is a girl on Argos, an intergenerational ship that is on a 592-year-long journey with a mission to reach a distant planet. Meanwhile, Zeno is an old man who is at the library afterhours, leading a group of kids in a rehearsal for a performance of Cloud Cuckoo Land. In present day (in 2020), Seymour is a 17-year-old environmental activist who tries to set off a bomb at the local library. Meanwhile, Omeir is a boy who is forced to join the Saracen army. In the 1400's in Constantinople, Anna is an orphan who finds a copy of Cloud Cuckoo Land in an abandoned priory library just before it is destroyed by Saracen forces.

It follows three sets of characters in different time periods who all come across a (fictional) ancient Greek tale called Cloud Cuckoo Land by Antonius Diogenes. The four-paragraph version: Cloud Cuckoo Land is about a book and how it manages to survive across time.
