Hero of the Fall - Alwyn Hamilton - Paperback

Rebel of the Sands, book 3

Once, there was a desert under siege, and no one to defend it...

The rebels are crushed: most are captured, burned out or dead. Except Amani, and it's up to her to protect the survivors. 

But how can one girl save a whole rebellion? Then foreign armies begin advancing across the desert plains and the Sultan starts hunting the rebels through the streets of Izman.

Now Amani must prove that she's not just a desert girl any more, that she's learned a few tricks since then. 

Here begins the battle for the throne.
