This was actually my book club book for the month. It's an area I have a background in, but I liked the book - it dealt with not just race but the intersection of race, class, racism, gender, anti-Semitism. It's quite a bit to read in one go, but luckily it is broken up into sections of 2-7 pages, which are pretty easily digestible.
Even with my background in anti-racist, anti-sexist thought, this book taught me things, plus gave me ways to talk about things that I have had trouble articulating. It would be the sort of thing I would keep on the shelf and refer back to later. (Except that I got it out of the library.)
Definitely a worthwhile read.
