Everyone tells Martha Friel she is clever and beautiful, a brilliant writer who has been loved every day of her adult life by one man, her husband Patrick. A gift, her mother once said, not everybody gets. So why is everything broken? Why is Martha - on the edge of 40 - friendless, practically jobless and so often sad? And why did Patrick decide to leave? Maybe there is something wrong with her. Something that broke when a little bomb went off in her brain, at 17, and left her changed in a way that no doctor or therapist has ever been able to explain. A Sunday Times Bestseller.
