Quick first reactions:

• The book is rather conventional in coverage and structure, though it does seem quite thorough and the information is concisely and densely presented
• It's a wilderness survival book - only a few pages on "disasters", and pretty skimpy info at that (not a surprise given the focus of his show)
• Lots of pictures from the show, lots of tie-ins with the show (though all good content, so not a complaint)
• The design is not great, particularly the choice of orange type for headers and an orange background with reverse white type for Les' tips, which as a result are a bit hard to read
• The gear checklists at the end contain no surprises or new info, but are solid lists and will be useful especially to those not already steeped in emergency preparedness

All in all, a fine addition to the library, at least based on my short time with it so far. I'll read it cover to cover and come back at some point with more observations.
