I opened this book with the wrong expectations; I was expecting narratives similar to Plant's videos, but found a technical how-to book (NB: it doesn't claim to be anything else).
Plant includes am impressive number of guides for making the tools you would need in a survival situation, particularly, a long-term survival situation. He does not include skills you would need that don't have a direct observable result (stealth, navigation, etc.), but those really require experience and an interactive teacher, rather than a book.
I would suggest that this book should serve mostly like a lab book in high school science courses: steps for replicating an experiment, and a reference for the expected result. Combining this with Plant's videos would produce a wonderful introduction to long-term wilderness survival without modern tools. Just don't rely on the book alone, and don't expect a narrative.
