Christina Hopkinson's new book is set in Islington and poses the question WHAT IS THE THING YOU HATE MOST ABOUT THE ONE YOU LOVE?
The book follows Mary’s life as she struggles to understand what it is exactly about Joel that make her angry - is it the way he doesn’t quite reach the laundry basket when he throws his dirty clothes at it or the fact that he never completely empties the dishwasher, but leaves the ‘difficult’ things for her to put away?
To win a copy of the book, just answer the question 'What is the thing most women said they love about their partners?' Enter via Facebook now.
