Written as an engrossing detective story by the leading authority on the subject, this is the first major account in nearly a century to deal with the core issues of how the Irish people came into being. Bringing together the evidence of archaeology, culture, tradition, genetics and linguistics to shed welcome new light on the age-old riddle of Irish origins, and illustrated with numerous informative line drawings and maps, this brilliantly argued book is essential reading for anyone interested in Ireland and the Irish.
