Query: Facinating subject, Yawner of a book

This book is more of a travel log than a text about megaliths. The author tells the story of his sea journey to visit European megalithic sites. At each site he provides a brief description of the megaliths and a bit of background information as well as his emotional reaction to the site and conclusions about which he has "no doubt".The information is too shallow and the author to opinionated for the book to be a useful text about megaliths. It does provide a good sense of the vast quantity of megalithic sites. It does also support well the author's premise of a shared European megathic culture.But I had to force myself to finish the book. More photographs and illustrations would have helped. Leaving out the bad poetry and fuzzy-wuzzy feelings would have helped. Leaving out the words "no doubt" (which he says over and over again) would have helped.The bibliography at the end is appreciated.
