City of Blaze (The Fireblade Array, #1)

The city is crumbling beneath a mountain of indulgences. Its soldiers find entertainment in the beds of the castle's servants rather than fight, believing they are safe from the deadly embrace of wielders. Wars are fought to encourage otherwise absent mortality, and countless citizens suffer the terrible pangs of nalka - the hunger for intimacy. All the while, Cadra's king concerns himself with choosing which of his disappointing concubines to execute next. The duty falls upon his son, Morghiad, to restore the city's strength and the army's purpose. As Morghiad attempts to do just that, he uncovers darker horrors and encounters a young servant who could either be his greatest ally or his greatest hindrance.
