Graceling by Kristin Cashore

Chapter One

           "In these dungeons the darkness was complete, but Katsa had a map in her mind. Once that had so far proven correct, as Oll's maps tended to do. Katsa ran her hand along the cold walls and counted the doors and passageways as she went. Turning when it was time to turn; stopping finally before an opening  that should contain a stairway leading down. She crouched and felt forward with her hands. There was a stone step, damp and slippery with moss, and another one below it. This was Oll's staircase then. She only hoped that when he and Giddon followed her with their torches, they would see the moss slime, and tread carefully, and not waken the dead by clattering headlong down the steps.
           Katsa slunk down on the stairway. One left turn and two right turns. She began to hear voices as she entered a corridor where the darkness flickered orange with the light of a torch set in the wall. Across from the torch was another corridor where, according to Oll, anywhere from two to ten guards should be standing watch before a certain cell at the passageway's end.
           These guards were Katsa's mission. It was for them that she had been sent first." Cashore, Kristin. Graceling. Orlando: Houghton Mifflin Harcourt, 2008.
