All in all, this was good to fine throughout with moments of excellence. This book commendably shifts attention to the woman left behind by the five men who perished with Scott on his return from the South Pole - mainly three widows and two mothers but others too. Original research pairs with a reconsideration of known sources to produce a work that is unique amongst polar narratives.
Telling this story from at least five different points of view (but many more in reality) was ambitious and creates many intriguing sub-plots and arcs within the wider story. The characters, contradictions, and scale involved creates a story that feels true to life. This is reinforced by the authors choice to write in the present tense in a style that resembles fiction with plenty of primary sources pasted in. This is done in such a way that seemingly doesn't compromise the work's historical integrity. The connections drawn between the woman were fascinating as the unifying tragedy and resulting grief contrasted with the woman's personalities, beliefs, responsibilities, class, and beliefs. (One surprising element was to discover the anti-suffrage attitudes of some of these women, especially in the case of Kathleen Scott.)
This ambition in scale and style leads to some of the drawbacks with Snow Widows. The style limits MacInnes' ability for more direct commentary and analysis at points. The many POVs could be considered disorientating or disappointing as you risk being taken away from your preferred characters. I found the pacing off in parts too, sometimes it lingered too long in duller parts and skipped over parts which seemed like they could've been expanded upon. Took too long to get to the actual tragedy, but from then on, the book is thoroughly and consistently excellent. I generally feel like some of the content could've been trimmed. I also have some questions about the footnoting, especially when it comes to citing apparent primary sources from secondary sources or from conversations the author had. I'm not marking her down for this as it may be my own misunderstanding.
Brilliant in parts, slow in some others but overall good. I feel like there was unrealised potential but overall I'm glad I've read it. May have additional enjoyment for those less familiar with Scott and his final expedition.
