There are a fair amount of photographs and maps to accompany the various stories. Best of all, there is a complete bibliography and very careful source notes. This book would be a great example to show students how sources should be cited, and demonstrate the careful attention to detail that was used in compiling this book.
Not only is this carefully researched, but like The Dark Game: True Spy Stories from Invisible Ink to CIA Moles (Candlwick, 2012), this is told in a fast paced, interesting narrative style. As much as I would prefer that this author go back to compiling poetry collections, he turns out high quality narrative nonfiction that adventure seeking readers will find hard to put down.
