Okay, this book was not what I expected. I will try to write this review without spoiling anything. It started a little slow but soon picked up and I started to get in to it. It was a bit like Nicholas Spark's 'Safe Haven' but if it was written as a thriller rather than a romance, and with a more straightforward prose. I liked how the writer portrayed his protagonists backstory, showing how she fell into that situation, and it really emphasised how easy it is with todays technology to take someone's freedom and make their world so tiny. It really seemed to pick up when it switched to the husbands point of view, and the big twist kept me reading, eager to know what had happened and how it was going to be resolved. But then there was another twist and suddenly it was like it was another story altogether, this one far less plausible and just full on weird, and I couldn't really take it seriously anymore. It did break the mold of what I was expecting from a story about a woman trapped in an abusive marriage, but I personally felt the two parts would have made more sense as two seperate, unrelated stories and the fact that they'd been written off was just odd. But that's just me. I don't read a lot of this genre so maybe someone who does and was expecting that mold would have found this twist exciting or unexpected. And I did really like the message that friendship can be a lifeline and lifesaving, championing sisterhood.
