The Ancient Wound - The First Einea Cycle, #1

From the oppressed mountain city of Cinura, two young adults - Alrik, a naturalist, and Lumi, a revolutionary - will flee. When they each return, it won't be in ways they expect. Alrik, falsely accused of terrorism after the mysterious death of a politician, runs for his life. On his journey to safety, he comes across secretive men and bizarre creatures, and begins to piece together who sought to silence him - and, more importantly, why.
Lumi, with a scrappy group of rebels, travels to the bottom of the world, the site of an ancient apocalypse, to gain a supernatural advantage in the coming conflict for her city. What she finds will have serious consequences for the world at large. Connected by a pair of arcane books of concerning origin, the two will make journeys across land, sea and sky - from the industrial smokestacks of Canalas City to the irradiated and frozen wastelands of Ollossos - and start to uncover trickery all over the world of Einea.
