Descent from Xanadu

the long version

Judd Crane is ruthless, sexually irresistible, the wealthiest man in the world ... and determined to conquer man's last frontier--eternal life. He pursues his dream on a dangerous, obsessive journey, from Yugoslavia to China, from his lush island to a secret atomic city in the Brazilian jungle. Crane is willing to spend billions, risk death, outwit foreign agents, lose his entire empire and the woman he loves ... until, at the moment of victory, he discovers the most important secret of all.
