"Larsen's book focuses on the Ceja de Selva, or high rainforest of central Peru, and its move in recent decades to what he categorizes as 'the post-frontier'. ... Larsen aims to bring out the complexity and contradictions of this situation, a task he accomplishes very effectively. ... an important piece of work, elucidating as it does the contemporary reality of an indigenous people that has implications beyond the Peruvian context."
