Melanie: "I'm really proud of how balanced the book is, how it captures both the male and female points of view. That's no accident. Oliver and I had to agree every word, so we argued loads while writing the book – from why it is that mothers often feel anger and resentment to whether men actually have lunch hours!
"These were probably arguments that only a brother-sister relationship could survive - if a couple had had them, it would have turned too personal. We only started to properly agree once we really started to understand what it’s like for each other. And that’s what I hope this book will do – help couples overcome problems and resentments or, even better, stop anger building up in the first place."
