Definately my favourite of the 3 newest ones. I had it read cover to cover without stopping, and thats because I didn't want to take my eyes of the page. The fast paced story telling means the whole book can be turned on its head in a single word!
Though there are parts for you to get your breath back, such as where you learn even more about Jack's elusive past and what the hell he got up to in that century stuck on Earth.
Spine chilling descriptions will have you only looking up from the book because you've heard a creak of the floorboards or a tapping on the windows, top tip for this book, don't read it whilst your alone, don't read at night. But, if you want a challenge, why not? I'd love to hear how you get on! Which from what I'm getting of the book, probably won't be too well.
As ever with Torchwood, i know you won't be able to resist!
