Desert of Doom — Rachael MacKay

Justice thwarted. An open sea of sand before her and a river of blood to her back, Alex Beckett now finds herself in one of the harshest environments in the known world: the Waste. A desert no one returns from stands between Beckett and the final resolution of her quest to make Samuel Garrett pay for his crimes. Garrett, safe for the time being, has enacted plans of his own. Beckett is not alone in this desert of doom.
