The Seekers of Fire: Book One of The Masters That Be

The Bers have ruled Mierenthia with fire magic and an iron fist for hundreds of years, but now their magic is failing. The firepipes are dry. The firewells gape cold and empty, and the factories are shutting down. Strange creatures appear at the edges of the world. Meet Linden and Rianor, who tamper with the half-ridiculed, half-forbidden idea of science, as well as those who stand in their way.
