Konrad Bantelmann is no expert when it comes to divorce.

But Fridz is all too familiar with it. For some time now Konrad has successfully avoided problems in general and girls in particular, but by a stroke of misfortune he somehow plants in Fridz's mind the idea of seeking revenge on her father's girlfriend, and is dragged into this red-headed girl's crusade of vengeance. And their secret weapon? Nothing other than an extraordinarily large rabbit. Funny, warm, and full of witty observations on family life, this is the story of Fridz and Konrad's madcap schemes and their new-found friendship.
