This is the first book I have read in ages on someone else's recommendation (thanks Charlotte!) and oh my god was it creepy (but good!). She recommended it because I was going through a bit of a thriller stage - she didn't say too much, just that she liked it, so I trusted her and added it to my basket.
When it arrived, I put it on my book pile and didn't think about it again until it reached the top and I picked it up to read. I didn't actually read the synopsis, or anything about it online, so the first few chapters were an adjustment to say the least... Basically, it is written from a psycho stalker's point of view, as he quickly becomes obsessed with a girl that walks into his bookshop and infiltrates her life.
I thought the book would shift perspective at some point, but it didn't - I also thought I found this too unsettling and would stop reading as I didn't like it because of this, but before I knew it, I had been sucked in and finished the book the morning after the evening I started it.
I don't want to ruin the story too much, but you can kind of guess where it ends up. I did actually find myself sympathising with the narrator at some points when he was sad because the girl he was seeing messed him around, and then shook myself out of it because he is absolutely horrific.
In short, this book is utterly creepy, and has the possibility to be quite believable - you may find yourself questioning those around you!
I definitely recommend it if you want to try something a bit far from the norm! Give me a shout on twitter with some of your recommendations!
