As daring and defiant as Kirk Douglas journeying 20,000 Leagues Under the Sea, there’s no stopping diver Hawk Ridley as he takes the plunge into an ocean of untold riches and danger. Fighting off ruthless rivals in search of gold is nothing new to Hawk . . . but fighting off a beautiful woman is a different story. Is she an innocent stowaway or a seductive saboteur? The answer comes Twenty Fathoms Down—as Hawk makes a discovery that will blow you out of the water. When it came to research, Hubbard was not one to head for the library. He always went to the source—in this case a U.S. navy deep-sea diver who agreed to show him the ropes and the danger. Hubbard admits it was daunting—even frightening—but he returned from the experience with all the first-hand knowledge he needed to fathom the true nature of life and death underwater.
