The Stone Builders

By John Lars Shoberg

Ten years after Humans and Wassarans have established a joint colony on the planet Ranklin, they discover an underground city hidden in the jungle. The entire city was built of stone, even the electronics. As the scientists study their find, looking to understand the unknown species who built it, strange things are happening in the jungle, and their crops are mutating, becoming un-useable. If they can’t figure out why this unknown species left their colony in a big hurry, they may have to abandon their own colony as well.
