Sarah Marquis
Sarah Marquis is a Swiss adventurer who spent three years crossing deserts and jungles alone, on foot with a cart carrying all she needs to survives.
Her journey from Siberia to Australia - portrayed in her new book Wild by Nature - took her across Mongolia and the Gobi desert, through Asia and back to Australia ending it in 2013 at a tree she befriended ten years before, to which she promised to return.
