Etched in Stone: Vimanas II

An indentured Celt in ancient times steals his master’s boat to sail to the new world in search of trade with rumored Norse colonies on the east coast of the North American continent. Blown off course by a hurricane, the adventurer and his men discover the mouth of the Mississippi River and follow it north. One of its many tributaries leads the Celt and his crew to a cave in western Oklahoma. Juil’s master, Laeg sails after Juil, and after a lengthy search returns him, along with a vast treasure in artifacts, back to Ireland.
In present time, Dan Crandell’s friend Zane, in an attempt to get Dan’s mind off a pressing personal problem, suggests they go inspect the mysterious writings in the rumored cave in Oklahoma. When Dan translates Juil’s stone carvings at the cave site, the two men embark on a mission to follow Juil’s ancient trail, marked in stone. The trail leads them west to areas of the Grand Canyon, which are strangely forbidden to public access. There, they find an old acquaintance, Dr. Julius Deaver, from a national museum in Washington involved in artifact theft and a governmental cover-up of ancient technology found hidden in deep underground caves far beneath the Canyon floor. Deaver and his cohorts capture the pair, and after a desperate escape through a maze of underground tunnels, they end up in an all out battle with Deaver, and elements of several government agencies to expose the dirty dealings of the national museum, and the thieves of a world changing new technology.
