Wanted: Assistant to provide maternity cover for high-powered TV producer. Must be bright, creative, with killer instincts. Emma would do anything to work for the woman who has the job she wants. Carrie is at the top of her game, with a dream career, a baby on the way, and a handsome screenwriter husband. For Emma, with parents who don't understand her ambition and a serious misstep behind her, this temp position might be her last chance. Carrie has given up more than anyone knows to get to the top of a ruthless business. She won't give up this baby too. But with Emma filling in for her at the office, her perfect life starts to unravel. Her bank account is inexplicably overdrawn, her husband seems strangely distant and colleagues are all too happy to take Emma's creative direction. Carrie finds herself dying to get back to work . . . until a letter left at her door changes everything.
