Wow like the cover and the title. I work in a office and have to commute by public transport so this really grabbed me instantly. What an intense preview why on earth is Martha sharing her secrets with a stranger on a train, and why on earth does Lisa respond by sharing hers! Recipe for disaster if you ask me! I have so many questions who is Martha really? Who is her boss? Who is Lisa’s husband and nanny? What does Martha want with Lisa? Keep your friends close and enemies closer comes to mind! Wow I need this book!
