I was completely drawn in from the start of this book. I have loved the multi-povs and short and snappy chapters. At the beginning of the book, we follow the sisters, Tasha and Alice, swapping locations and lives for a week. We then have their respective other halves, Kyle and Aaron. Alice and Aaron are looking forward to their break, whilst Tasha's sister is looking after their twins and giving this couple their much-needed break. Unfortunately, on this evening of the swap, there's a break-in, and Kyle is sadly murdered, and Alice has been attacked and is in hospital; now rushing back, Tasha has found a note saying, 'its the wrong sister' Although near the end I did guess some of the plot twists I still really enjoyed this book and the wrap up was fantastically done.
