The book Desmond was reading on the plane was Haroun and the Sea of Stories by Salman Rushdie.

Wiki states :

"Haroun and the Sea of Stories is a 1990 children's book[1] by Salman Rushdie. It was Rushdie's first novel after The Satanic Verses. It is a phantasmagorical story set in a city so old and ruinous that it has forgotten its name.[2]"

The book includes the following things:

- an ancient city so old that people forgot it existed
- a war between the rulers of that ancient city
- a main character who is represented by two sides of himself: an "anthropomorphic shadow" and a "diminished man"
