I think that for me the biggest drawback to this book is the sectarianism of its subjects. Of the 16 people featured in this book by Vicki Mackenzie (herself a Tibetan Buddhist) all but 4 are Tibetan Buddhists, two of them being Theravaden and of the remaining two, Stephen Batchelor was once a Tibetan Buddhist monk and Yvonne Rand is married to a Tibetan Buddhist and say she practices that alongside the Zen for which she is better known. I do think the author could have made more effort to also talk to Westerners who had found themselves drawn to other forms of Buddhism, notably (because it arguably has the largest number of adherents in the West) Zen Buddhism, and explain that there are other ways of experiencing the Buddhist teachings than the way in which it is interpreted in Tibet, which is idiosyncratic to say the least.
That aside, on the whole her interviewees were interesting enough, and had certainly varied in the ways in which they incorporated Buddhist teachings into a "Western" setting and culture, and there is enough general information about Buddhism to attract and inform people who know very little to begin with. Perhaps the two I found most intriguing of those she talked to were Michael Roach, who is a very successful diamond merchant as well as being a Buddhist monk and Sister Kovida, whose humility and understanding of the dharma made quite an impact on more.
Having been riveted by her book "Cave In The Snow", a true story of a really remarkable English woman Tenzin Palmo (formerly Diane Perry), this was never going to be as good, but the stories in it do shed some light on how, why and when Buddhism started to become popular in the West, and as such it is a valuable record.
