Livira grew up in a huddle of huts out on the Dust. A place of hand-to-mouth existence, plagued by creatures living within the Dust, and Sabbers attacking from without. It's one of these attacks that leads Livira to a new future; to the city of Crath and the library there.
Evar and his family live in another library, one which they cannot leave. They've food and water, and all the books they could ever read, but Evar longs for escape.
The two meet in a place between worlds; somewhere outside the normal boundaries of time and/or space, and from which they can travel to multiple other worlds. Are Livira's and Evar's home libraries in the same world but at different times, or at the same time on different worlds? In Evar's world civilisation has fallen to the Sabbers; in Livira's it looks like it will happen soon. Is there a way to avoid the cycle of rise and destruction that plaques both worlds.
This is a book which starts out simply with Livira being forced from her home and resettling in the city, but which gradually expands to bring in themes of love crossing all boundaries, of the danger of having unlimited knowledge without checks and curbs on its use, of who should limit that knowledge, of mankind's destiny to repeat its mistakes again and again. The plot twists and turns through time so much that I was left dizzy, but I thoroughly enjoyed it. As Book 1 of a series, not everything is nicely tied off at the end, and I can't wait to read 'whats happens next'.
A great startb to a new trilogy from Mark Lawrence.
