One book I thought I wouldn’t like but ended up loving is The Mortal Instruments: City of Bones. I talk about it more in my review but it was something I had wanted to read for ages but just wasn’t sure if I would like it. I was very wrong. I loved it so much I read it in the space of a couple of days and ended up buying the rest of the series. (Sadly I still haven’t had time to read past the 3rd novel)
