This is a book by an author truely absorbed in his subject.
The narrative is clear and interesting, incorporating aspects of events and personalities to provide a clear picture of the Welsh Power Culture which gave rise to Henry VII's victory.
The book describes Owain Glyn Dwr and his contributions to founding of Welsh identity. It also describes how the 'Seers' or prophets fore-told of a Welsh hero, hence Son of Prophecy.
It tracks the ascendance of the Yorkist cause with the help of charecters such as Gruffyd Ap Nicholas a shrewd and influentential Welsh landowner. Efforts culminate in 'The Battle of Bosworth'.
Richard III deposition is also covered in some detail; the Duke of Bukingham's failed attempt to usurp him, Herny VII's flight to France, and later his return to re-claim the crown.
I would highly recommend this book to anyone interested in history in general. If all history books were as well written as this, the subject would be a lot more popular.
