Swedish title: Slå tillbaka! En handbok i självförsvar för kvinnor.

The book was published by Natur och Kultur publishing house in 1993 and a revised version in 1998. The book covers the basics of the Self-Defence programme that Petra developed during her years as a Self-Defence teacher.

The theoretical part of the book underwent a major revision between the first and second editions. In the first edition Petra is clearly influenced by radical feminist analysis of male violence and domination over women. Already at that stage however, she doubted that this theory accurately described the reality. She knew about the existence of partner abuse in same sex couples and also about homosexual pornography - things the radical feminist theory has difficulties explaining.

Another difference between the two editions is the physical techniques covered. In the first edition Petra describe a wide range of kicks and blows, and what sensitive parts of the body one should aim for. In the latter edition there are fewer such descriptions, since she felt it more practical to teach fewer, easy-to-learn techniques for better effect.
