The Sehret Chronicles - C F Barrows - Bog

Three hundred years ago, the Rhenor nation split into two, the Reshan and the Khanor. One dwells in the Outerlands, the other in the mountains - and although the nations have made peace, their people have not. One fateful day, two small patrols meet in an outer cave in Khanor territory. The youths, spurred by mutual distrust, brawl, and the ensuing cave-in cuts off their main routes back to both the Reshan and the Khanor civilizations. Their only choice is to join forces and follow the one remaining tunnel - one that runs through an area known simply as the Forbidden Regions - to find their way back to their homes. Along the way, the beliefs of every traveler are put to the test, and the secrets of a few may threaten the safety of all. For as they go, Lusefar, lord of the Saethen, sends his agents against them, licking his lips as a ravenous dragon.
