It's a great idea to collect the best ridges in Scotland into one book and it turns out there isn't space for them all in this one book - the appendix lists another 40 odd (mainly climbs). The book is written with a marvelous energy and joie de vivre that really draws you in; the maps are great and the photos too. It's a lovely book. I am a walker, not a climber, and, despite the subtitle, there are many routes in here suitable for reasonably experienced hillwalkers with a good head for heights. Do the winter routes as summer walks and Creise, Ring of Steall, Aonach Eagach, Liathach and many others become accessible to us mortals. Some additional route planning to cut out short climbing sections also opens up a number of the other routes given. Of course a good number of the routes are serious climbs. You'll never find me on Tower Ridge Ben Nevis, but, in summer, you might find me on the adjoining Ledge Route. Fantastic book, highly recommended to all who love the Scottish highlands.
