“Into a Dark Frontier is an international thriller of rare depth and complexity that would make the likes of John Le Carre and Robert Ludlum proud. But John Mangan goes both of them one better by injecting into the mix a loner hero with a gunfighter mentality fit for taming continents as well as frontiers, with Africa subbing for the Old West. A vision splendidly realized and tale wondrously executed.” ―Jon Land, USA Today bestselling author
