Two Fang Gap

Publisher's blurb:

Two tree-sided mountains rise above the low hills of this area, giving it its name. The peaks and surrounding hills are divided by a broad grassy valley and the deep, slow-moving Two Fang River. An ancient bridge decorated with stone gargoyles is the only obvious way across its dark waters. Rumors surround Two Fang Gap, rumors of battles and burial mounds, ruined towers and flying horrors. Only the bold will find out which are true and which are false.
