This isn't a particularly well-written book, and it's not the only meditation book you should own or read. Having said that, it's accessible and gets the job done. One of its strengths is its 'groundedness.' You get the sense that Piver is pretty much like yourself and that, therefore, what she's suggesting you do -- establish a disciplined meditation practice -- may well be as helpful to you as it has been to her. She also brings a sense of joy to her expression of her meditation practice that spills over to the reader -- not an insignificant thing. Lastly, she includes concrete how-to instructions on various meditation exercises, as well as a 7-day meditation program that sounds eminently sensible.
The one dissonant note, I think, is the emphasis on fear. To me, this is more of a marketing device. Meditation, Piver's take on it, and her instructions for it, address just about any psychic/emotional issue that a reader might have, not simply fear. That, however, is a very small quibble about a useful book.
