Hi Colin,
Welcome here and to this wonderful hobby.
I have this book and it is a great "guide" book to search for the constellations. It guides you by star hopping using dotted lines and numbered stars. Very easy to read and understand. The back section of this book is dedicated to explaining the legends behind the constellations - fascinating reading!
Just a note, that the above book doesn't contain maps and objects of interest. If you are after something along these lines, may I suggest "The Southern Sky Guide", by David Ellyard & Wil Tirion. It's filled with easy to read maps where each page describes the objects of interest for that map page. I was nearly going to suggest another terrific book I have and then realised it only gave one diagram of the constellation per page, where as the book I just mentioned, actually shows you the surrounding constellations as well on every page (easier to plot your way around), which I think maybe more helpful when you are viewing unfamiliar skies.
Enjoy our wonderful skies!
