I very much loved White's Ar'N't I A Woman, which was a history of slave women in the plantation south. So, I was pleased to learn that White had also pursued a history of the black women's club movements of the late 1800 - 1950s.
White does a fantastic job of documenting the many ins and outs of this movement, which should really be referred to as movements (or, perhaps, movement with a "the" in front of it -- a practice bell hooks as promoted with regard to speaking about feminist movement, rather than THE feminist movement). She examines the forces these women were up against, including examining how they could sometimes be their own worst enemy. Here, she also looks at the ways systematic forms of inequality among black women shaped interactions between club women, and among various factions with just one club: class, regional, and gender differences (the latter emerge when women's club work was a part of larger movements for racial uplift).
My only criticism is that, unlike Ar'N't I A Woman, this book seems to have no overall narrative or story that ties it all together. Gray's earlier book was driven by a couple of basic concepts which she illuminated through the detailed historiography of black female identity in the plantation south. In Too Heavy A Load, White doesn't seem to have a message or two she wants to convey. For me, this makes the book feel more like a survey of the history, where it's sometimes too easy to get lost noticing the details of individual trees, unaware of the broader outlines of the forest.
