When five very different mothers met in their NCT class three years ago, they had no idea that their lives were to become inextricably entwined.There's Bella, stay-at-home mum of Teddy. She suffered postpartum psychosis after Teddy's birth. There's Chrissy, divorce lawyer, married to Russell. They're having some problems with their sex life. There's Electra, mother to twins, who is struggling with her son's behaviour. There's Skye, a single mother, who used a sperm donor to have her baby. Then there's Jen. She was supposed to be a mother, but it hasn't worked out like she expected.   In fact, nothing has worked out quite like any of them expected, and now Bella's husband is missing - after stealing a life-changing amount of money from the accountancy he works at. The police want to get to the bottom of what happened, yet the five women seem to be hiding something. But what are they hiding? What secrets could possibly be holding these very different women together?  For fans of Big Little Lies, Friend Request and He Said/She Said, this is first-class psychological suspense from the critically acclaimed Sarah J Naughton.
