I just finished The Miocene Arrow by Sean Mcmullen, the second book in his low tech, far future trilogy.

Set in a complex, and fairly original, world, this trilogy explores ways limited technology can be used to mimic higher technology. For example, in the first book, wind engines and a computer built out of human components feature heavily. In the second book, it is simple gasoline engines and heavier than air aircraft.

They are both interesting books, but the number of new characters and locations with weird names swamps the reader at the start. With persistence, it mostly becomes clear but Mcmullen's prose is sometimes too vague to follow well.
