Meet the Newells, a big family of good lookers and hard grafters. From their sleepy working class backwater, the siblings break into Oxford academia, London's high life, the glossy world of magazine publishing and the stratospheric riches of New York's hedge funds.

Then there's Paddy, the wrong'un in their midst, who prefers life's underbelly.

As things fall apart around his sister Bea, is Paddy behind it all? And why does matriarch Edie turn a blind eye to her son's malevolence? Will she stand by and watch while he wrecks the lives of her other children? Just how much is she willing to sacrifice to protect her son?

The book opens with Edie, now in her seventies, who looks back on her early married life with her husband, George, and their ever-growing brood. She loved having babies, but resented their growth and increasing independence. She recalls the horror and confusion surrounding the death of her toddler son, Timmy. Even though it happened forty years ago, she still blames her brother, his uncle, for falling asleep while he was supposed to be looking after the children. Now, her favourite son, Paddy, has just been released from prison for dangerous driving. She is good at making excuses for him. All her other children are successful, and have done extremely well in their chosen careers, but it becomes apparent that she begrudges her only daughter's success. Why does she resent her daughter so much?

Paddy is malevolent, violent, bullying, cruel... Edie has never forgiven herself for giving him up to the care system before she married George. He has never fitted in with his siblings, and is the bad apple that can ruin the whole batch. The only person he has ever cared about is his stepfather, George, who saw only too clearly what Edie has always been blind to.

Bea, the only daughter in the family, has grown up knowing her mother doesn't love her. She is a successful journalist, and adores her husband, David, and her stepchildren, but longs for a baby of her own. Then suddenly David dies. In the midst of her grief, her glamorous cleaning lady, Lorena, flaunts her pregnancy. She insists that the baby is David's, and is willing to take a DNA test to prove it.

Welcome to the world of the Newells, where nothing is as it seems.
