We call it the Great Escape. The annual trip where my boss asks us expert travel guides to escort a group of privileged, uber-wealthy clientele on some far-flung expedition, a cut-throat contest for riches and glory.The stakes have never been higher, nor the challenge harder: I must summit Mount Kilimanjaro before my rival guide to win the ultimate prize.But this once-in-a-lifetime trip was never about winning to me. I'm here for answers, even if no one is ready to give them up. By the time we reach the top I will have the truth, if it kills me.
