I was unsure about this book before I started reading (thought it might be a bit chick-lit ish) but I'm glad I tried it, as I enjoyed it greatly.
The story starts with four different characters (Katya, Cathy, Alexa and Sandy) each having a chapter which sets out where they are in their life now and the choices and repercussions that have led them to this point. The following chapters then go backwards through the timeline of their lives to life changing decisions.
This is a story of 'what if' - what if you'd treated this person differently, what if you'd gone left instead of right etc - and works really well. All the characters were believable (so much so that I really felt like banging their heads together at times) and all their seperate stories are different enough that you don't forget who is who). A very clever story indeed and well told.
It is not just a story for ladies, it is a story for all - so, ladies, pass it on to the man in your life when you've finished it.
