Today, I was able to purchase the Kindle version of the book, and have given it a once-through reading. Probably missing much.
Overall, I'd have to say that his pūrva pakṣa is successful. I particularly like the chapter on 'Non-translatable Sanskrit versus Digestion', where he gets very specific in dispelling some of the more disastrous English translations of Sanskrit terms. It will take at least another pass at the two appendices to get a good grasp of those, but this line from 'Appendix A: The Integral Unity of Dharma', caught my eye:
The spirit of openness toward the multiplicity of possible answers to complex questions is why pluralism is deeply embedded in the notion of dharma.
The Judeo-Christian religions lack the fundamental R&D to be able to change to the same extent and to be able to offer the same choices and openness. As we have seen, they do not believe that the first principles of truth can be discovered by humans on their own; hence, their obsession with claiming historically unique events.

Here, as in other places, there are over-simplifications (as he admits early-on). There are both Judeo and Christian (as well as Islamic) mystics who have done some of the 'R&D' (as he calls experiential introspection) to 'open up' those traditions, but they are far from considered 'main stream'. Of course, there are variations of 'Hinduism' which are much more in line with Abrahamic monotheism, but Indian peoples tend to be much more open to religious diversity and accepting of 'individualistic' (in Western terms) 'inner experience'.
