This one was a let down for me. Though the subject matter is something I believe in, I just feel like it's been done so much better, likely because this came out in 2005 and more developments and texts have come out since then. Though historical context is important, this book seemed to have too much of it, making it dense and tedious to sift through. It also occurred to me multiple times that Sullivan seems to lack original ideas, and instead uses this text to primarily weave sources together like an entirely too long literature review.
