Rebel of the Sands Tome 3
Hero at the Fall

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 final battle for the throne. Who will lead, who will triumph, who will live and who will die ? All heroes are mortal in the end...
