Having led cross-cultural programs for teenagers, I enjoyed this book and its firsthand accounts from gap year students about their experiences. O'Shea places these accounts in a context of psychological development and pedegogy, and the book was heavier on academic analysis than I expected (although since O'Shea is a professor of education, maybe I shouldn't have been surprised?). As a former teacher, I also enjoyed the somewhat dense analysis sections, but can imagine those are a bit heavy for other readers.
The accounts are deliberately narrow, focused mainly on one-year international volunteering gap experiences with western/UK-based teenagers going to developing countries. For that reason, I thought the book title was a bit misleading. "Gap Year: A Qualitative Analysis of Post-Secondary Service Years in the Developing World" seems more accurate, so be forewarned. All told, for those students interested in a Peace Corps-type gap year, this has some valuable perspectives and insights.
