There's nobody like your sister when things go wrong. At least that's what Ali hopes as she flees America and a broken marriage. Emma will surely take her and her kids in, and it'll be just like old times, right? But the last thing Emma needs right now is her sister descending upon of her. Not when she's recovering from some earth-shattering news of her own. How can she tell Ali her secret, when she can't even get her head around it herself? Ali and Emma want to pick up where they left off - but it's not going to be easy.
