The Matchbox Reaper 3: Sands of Bay-9.. The Matchbox Reaper, #3

The desert sands hold more than just heat, they hold the debts of the dying. After the smoke clears from the obliteration of the red-hair farm, Cairo Jenson finds himself the reluctant guide for a group of rebels on the run. Their destination... the Bay-9 capital, a walled sanctuary ruled by the gluttonous and unpredictable Balm Speckler. As Lord Raffaello and his generals recover from their wounds, Cairo is drawn into the dark histories of his companions.
From Colonel Kurban's blood-soaked past to the terrifying implications of the LAN's new "smart" surveillance technology, the cost of resistance is becoming clear. When a routine medical visit turns into a high-stakes extraction, the city erupts into a battlefield of magic, fire, and steel.
