I will certainly not recommend it as a first book on Hinduism. For that I would probably go with http://www.amazon.com/Philosophies-Religions-India-Yogi-Rama... . It's a short and concise read and the treatment is a good mix of outsider (the writer is originally a westerner) and insider (he also happens to be a hindu).

As a second book, The Hindus is pretty accessible if you're used to reading slightly technical books. Her style is good, and she's absorbed the Indian philosophical writing tradition of using far too many analogies :)
