The burning kingdoms

"King Aloysius is mining powerful demon smoke and using it to fuel an unstoppable army of children. . . The demon hunter Tash is trapped, perhaps dead, in the demon world. The illegitimate prince Edyon has finally met the father he never knew, and it may be the worst thing to ever happen to him. The servant March is banished after his betrayal of Edyon. The soldier Ambrose is injured, isolated, and heartbroken. The princess Catherine is becoming more and more like her heartless father as she tries to wield control over her new kingdom. Aloysius' smoke-powered boy army will kill every last one of them in his quest to conquor the world. But what nobody knows is that there's more to smoke than meets the eye"--Provided by publisher.
