"A fascinating insight into Ireland's ancient burial sites" - Irish Independent; "A monument" - Drogheda Independent; "The sheer amount of information contained within the book is mind-boggling. It is well thought out and structured . . . The more you read the evidence the more convinced you become." - Astronomy & Space magazine; "It is a beautiful book and very well written. The information that you collected is outstanding." - Barbara Carter, co-author, The Myth of the Year and The Goddess and the Bull; "The authors . . . reach interesting and challenging conclusions about the significance of ancient astronomical knowledge. The book is jammed with colour illustrations, maps and photographs. A thoroughly interesting read!" - Archaeology Ireland; "An essential book that demonstrates just how much the beliefs and practices of our ancestors were influenced by the movement of the stars, in particular those of the constellation Cygnus - the celestial swan and Northern Cross - once seen as a source of life and the destination of the soul in death. A must have tome for all those passionate about what remains of our fast disappearing ritual monuments of the prehistoric age." - Andrew Collins, author of The Cygnus Mystery; "Refreshing and fascinating . . . a wonderful magical book, sumptuously illustrated and a must for anyone who loves to delve deep into our past." - Kenny's Irish Bookshop; "What an amazing adventure it is to read this precious book!" - A reviewer on www.amazon.co.uk, one of a number who gave it five stars.
