The Sherangivan by Jacqueline Fellows

"You go no farther than your own mind; and what could be more familiar to you than yourself?" A new city on the rivers, its walls pristine and untested. Encroaching strangers, aggressive, seeking a new land of their own. A brutal triple murder in the woods. And a young man caught in the middle of it all, tormented by dreams he doesn't understand.
