Yay, a book for adults! Hehe.
I pretty much couldn't put this book down. I stopped watching tv and pretty much ignored google reader until I'd finished it.
So, in other words, it was good!
The book is about a couple who are (as becomes clear quite early on) not entirely happily married, and what happens when the wife, Amy, goes missing. It's told from the husband's point of view, and also through Amy's old diary entries. And if you haven't heard anything else about it, then I suggest that you don't read the rest of this review and go and read it immediately, so you can stay unspoiled for it. I only had vague inklings of what might happen, and I kind of wish that I hadn't had those.
Read it! Go go go!
..And now for people who aren't afraid of spoilery rambling (or who have read the book!)...
I really enjoy books with unreliable narrators. And this one has 2! So, yay! Although I was expecting the first twist (I didn't know exactly what would happen, but I knew that all was not as it seemed), I was definitely not expecting to have my alliances shift so often when reading it. (Although by the end, they were completely fixed).. I started off finding both Nick and Amy fairly sympathetic, and halfway through I had no idea what to think anymore.
I don't think that the book is a great work of fiction, but it was nicely written and nicely plotted, and left me wanting to skive work and carry on reading (I didn't! Well done me), so I would definitely recommend it!
