Former Navy SEAL and lifelong adventurer Marc Lonergan-Hertel thinks his latest mission is to be a sniper in the jungles of South America—but he finds that’s merely a stepping-stone to his true purpose in life of protecting the vulnerable people he encounters when operating alone and in dangerous places. …a large wave buries the bow of Seamaster and I am exhaling bubbles into the ocean as I try to call for help. And then I am hit with a distinct sensation—I can no longer breathe… This and other incredible adventures are shared in SIERRA TWO, the true story of one man’s literal and metaphysical journeys. In the end, it’s a story about about embarking on a mission greater than oneself—a journey of finding the value in your life and of the responsibilities of following your true life’s path as a protector of others, no matter what the cost. On a river code named SIERRA TWO, Marc Lonergan-Hertel is seriously wounded after he loses his jungle guide to a violent death in the “lost world” of the Amazon. At his lowest moment of scouting a three thousand-mile journey for a National Geographic television show in one of the last remaining biosphere reserves in the Guiana Shield, he is befriended by a lost indigenous child and an old shaman from an ancient tribe. In an act that seems like repayment for his earlier sacrifices in the cities and slums of Brazil, the shaman saves his life and gives Marc an ominous warning—death will follow the former SEAL through the steaming jungles.
