From publisher blurb:
Early one chill morning, a fisherman discovered a collection of unusually large scales, dried fins, and flattened pieces of reed strung together with moldy netting washed up on the shore of Lake Pethegas. He believed it to be nothing but flotsam, but as he approached, he noticed faint markings of an unknown language scribbled upon its pieces. The words seemed to twist and writhe of their own accord, and the fisherman ran screaming from the lakeside. To this day, he grows pale at the sight of any large body of water.
