The authors of this book approach their subject with a medical and scientific background and relate their evidence about the people of the long barrows of Britain in this light. This book complimented other books on this subject which I have bought and read over recent months. Anyone who has enjoyed reading the excellent books Temples of Stone, Neolithic Britain and Ireland, The Dolmens and Passage of Sweden, and Earthen Long Barrows will like this book too. The most appealing aspect to this book is the scientific way that evidence about prehistoric sites is analysed and presented with conclusions restricted to what can be proven rather than extrapolated to uncertain lengths as can occur sometimes when archaeologist authors imaginations run away with them. The book is obviously of a specialist interest nature, but as a lay person I would recommend it to anyone who has a more than passing interest in prehistoric matters. Like a number of similar books I am always surprised at the lack of detailed comparison of similar sites across Europe.
