Rise of the Arcadians — T.C. McMullen

Can you survive? It's the year 2122, seventy-two years after the Upheaval that changed the world. The Earth is nothing like it once was - rivers became oceans, waters washed away sands and soil to leave jagged cliffs, earthquakes reformed mountain chains, northern lands froze, and technology was lost or without resources to continue. Humanity struggles on. Farming and protecting the wall guarding civilized borders from cannibalistic outsiders called the Oceaners are the main priorities. One stone citadel full of armed forces stands outside the wall's center. Two more stand at the northern and southern borders. But good men to fill them are scarce. Desire, trusted scout to the citadel leader, sees to the welfare of the east citadel men while remaining a mystery to all. She knows much about humanity's past and things of the future before they happen. She also knows secrets of the haunted outer lands everyone else fears. When Oceaners band their forces to unconquerable numbers, she must fight to help save the people of the civilized lands, but her home village and its citizens, ghosts of the wilds, may be the world's only remaining formidable force if they can escape their own demise from within.
