I tried reading this book several times, but could not survive more than a dozen pages. It suffers from several severe disadvantages:
1. Although the author declares that "The book is written for students", he assumes for some reason an extremely broad background, from the basic terminology of supersymmetry to thorough knowledge of the two-mode squeezed state. This problem alone made the book almost worthless for me.
2. The derivations are over-complex, involve multiple variable changes, and rely on many unexplained assumptions. I usually lost the track after three steps.
3. You hardly find a page without a typo, some of them with crucial implications.
Therefore, if one wishes to learn supersymmetry in quantum mechanics, I would recommend Junker's book instead, or, if interested in the topic more from the quantum mechanical viewpoint, the book of Cooper, Khare and Sukhatme.
The only good thing about this book is that it contains a plethora of references, to sources that most probably explain a wide array of subjects much better than this book does.
