IT WAITS BELOW is a lusty, piratical, high-seas adventure with science fiction flourishes. An expensive expedition in a deep-sea submersible in the Indian Ocean is designed to search out, and recover, tremendous quantities of gold lost in a 19th century shipwreck. Actually the incident was not a wreck per second, but a vanishing. No note was taken of the loss of the treasure ship in records, till a 21st century salvager discovered it. If he had known the cause, perhaps he would have left the wreck on the ocean's floor. My favorite portion was the Prologue, which is lyrically imaged and tremendously vivid (and implacable).
