Blurb: “The "New Sea" was teeming with a secret life. It was the greatest engineering feat -- the flooding of part of the Sahara Desert. But the new waters that covered up the land also threatened to destroy an ancient, secret civilization beneath the earth. When Mark Sunnet's plane crashed into the New Sea, he and his beautiful companion, Margaret Lawn, were taken prisoner by these secret people. They were taken deep beneath the earth into strange, dark caverns. Caverns that seemed to hold no hope for escape. But Mark and Margaret had to escape. For now, suddenly, they were faced with two terrors -- the secret people who were to be their executioners and the merciless New Sea that threatened to kill them all. . . .”
