'Who is Nina and what is she doing with my husband?'

I was hooked from the very beginning. I love the way the author describes Cressida in such detail which shows her vulnerability and she finds it very hard to control her young daughter. The build up to the phone call between her and Lawrence, her husband is very gripping. Cressida keeps asking herself' Who is Nina?' She intends to find our secretly through the help of a friends sister, Brioni. I am very excited to read on. Will Brioni find out who Nina is and if she and Lawrence are hiding any secrets from Cressida?How will Cressida react if so? With devastating consequences? I am desperate to find out!
