This is, or should become, a standard work for all of us. The laborious research that Pines undertook comes across in the first part, which is somewhat statistical. But don't let that put you off because the meal proper begins with Part Two. This is as unputdownable as any thriller and if by the end of it you're not jumping up and down and saying to yourself "So THIS is how it works!" then you're probably already a psychotherapist. In fact I showed mine the chapter on Attachment Theory (never better explained) and he promptly went and ordered two copies himself. Buy this book if you've ever been in love, still are, or are planning to be.
