They left a man behind. 100,000 years behind. Another chapter in the popular time travel thriller series Bad Times by bestselling author Chuck Dixon. Lee, Jimbo and the rest of the hard-fighting Rangers go back to prehistoric Nevada to find the man they left behind on their first mission. This epic quest brings them into dangerous encounters with giant predators long extinct. But the most dangerous of all these animals is man. Back in the present, one of their team is abducted by a mysterious billionaire seeking to grow his fortunes with the use of the scientific miracle known as the Tauber Tube. Also, their benefactor from the future shares a startling secret. The millennium-spanning saga by the author of Levon's Trade and Winterworld: The Mechanic's Song continues here! "Chuck is a damn good writer who is really good at hooking you, giving you fun characters, and telling you one hell of an adventure story." Larry Correia, Monster Hunters International, the Grimoir Chronicles "An intelligent and well thought-out high action time travel story." Noah Mullette-Gillman, Luminous and Ominous "Dixon excels at putting down action, of introducing larger-than-life heroes, kicking them through the door into a big mess, and having them sort out a situation in a flurry of martial arts moves and big guns." Mel Odom, The Rover series. Helldorado was previously published as part of One Helluva Bad Time
