How to be a good wife

This is a powerful, original and haunting debut: hard to put down and impossible to forget. I know what my husband would say: that I have too much time on my hands; that I need to keep myself busy. That I need to take my medication. Empty nest syndrome, he tells his friends at the pub, his mother. He's always said I have a vivid imagination. Marta and Hector have been married for a long time. So long that she finds it difficult to remember her life before him. He has always taken care of her, and she has always done everything she can to be a good wife. But now Marta is starting to doubt her life with Hector. A blonde girl has appeared in the shadows, and she seems to be telling her something. Is Marta hallucinating? Or could this be a memory, rising to the surface...?
