You can trust her with your child, but can you trust her with your husband?

Clare Elias has always known the risks of being married to a rich, handsome, younger man like Marc. But when she gives birth to two gorgeous babies, she discovers motherhood isn't quite the cinch she'd expected, yet Marc takes to parenthood like a duck to water. Desperate to regain her independence running a successful chain of boutique flower shops, Clare hires Jenna, a confident, efficient nanny keen to escape a relationship that is going horribly wrong.

But before too long, a deadly rivalry emerges, and as events spiral out of control, Clare finds herself forced to make painful decisions about love, loyalty and motherhood.
