This is a very interesting book containing insider information about the laborious and complex negotiations that brought peace and stability to Northern Ireland after years of conflict. Written by Jonathon Powell, Tony Blair's Chief of Staff throughout his period as Prime Minister, the author had a pivotal role within the peace negotiations and saw and heard things that few others will have witnessed. The book is written in an engaging and interesting style, and Powell clearly has cordial and constructive relations with some controversial figures, particularly Gerry Adams and Martin McGuinness. The friendly camaraderie often evident in his exchanges with Sinn Fein leaders in particular has caused some concern to unionist commentators in particular. Powell however always emphasises the even-handed approach of the British government, even if the rival sides did not always see it that way. Powell has used his role to provide some previously unknown information such as the existence of a secret channel of communication between the ostensibly hostile groups, Sinn Fein and the DUP. This book is a vital read to any serious student of modern political history and of the Northern Ireland problem.
