First published in 1979, this book has had quite the impact from that time onwards and has been re-issued several times with new information on the topic. I happen to have read the 2009 edition, which is testament to the importance of the book, for it to be deemed worthy of re-issue and revision to this day. The subject is certainly a remarkable character within history, taking on a role that was not just traditionally, but exclusively masculine, and occupying that space without compromising her own femininity; not the conventional tales you expect to be hearing from the histories of 16th century Gaelic society.
Before the book starts the story of Granuaile (or Grace, or Granny...), the reader is briefed with a quick context of Irish society. Talking about pre-Medieval, Medieval and also Early Modern Ireland, the foundations are laid in an accessible not-dense way for the tale of Granuaile to be understood within. Several key concepts, such as the system of clans, and English presence in Ireland are crucial, therefore their explanation beforehand is vital.
The rest of the book runs as a roughly chronological account of Granuaile's life, but not as one linear narrative. The chronology jumps back and forth mildly to fit in with the topic that it is describing, and this keeps the prose cogent and easier to follow.
The way that Granuaile is discussed, is sufficiently balanced; however perhaps a little much on the positive side of the bias scale, however this isn't too pervasive. She's never portrayed through sainthood or worship. It could be said that there is a tendency to criticise the actions of the English, however this can also be seen as somewhat justified considering their acquisitive actions and xenophobic beliefs regarding the Irish as people.
The books is also very brief, the main body comprising Granuaile's chronology reaching only around 150 pages. This is understandable given the scarcity of historical record within Irish clans, especially as she was a woman who wasn't commented on much in retrospect after her death had passed by those unwilling to attribute political significance to 'the fairer sex'. Thankfully, the appendices are utilised to record fascinating historical documents and poems that concern Granuaile. The shortness of the book also makes it an accessible read, and this may explain how it has been used within the Irish history curriculum.
Overall, this was a fascinating read about a divergent woman. Pirate; mother; political negotiator; not actually a Queen, but who needs such a superficial title when you're as interesting as Granuaile?
