Following the route taken by British explorer Ivan Champion in 1927, and amid the breathtaking landscapes and wildlife, Salak travelled across this remote Pacific island - often called the last frontier of adventure travel - by dugout canoe and on foot. Along the way, she stayed in a village where cannibalism was still practised behind the backs of the missionaries, met the leader of the OPM, the separatist guerrilla movement opposing the Indonesian occupation of Western New Guinea, and undertook an epic trek through the jungle. Four Corners is also an exploration of the author's dysfunctional family past and the demons that drove her to experience situations that most of us can barely imagine.
