This book, I was hooked from the first impression. Whilst this is quite a lengthy book, at nearly 500 pages it is longer than most non fiction books I have read recently, it is so well written and a fast paced book that it had me captivated as soon as I picked it up. The main characters Rob and Kate are completely believable and you instantly feel drawn to them and are left wanting to know more from the outset. The storyline is believable and even though it is a similar concept that has been touched on by other writers that does not detract from the brilliance of this book. This is not an author that I had read before but after this I will absolutely look to read others he has written. Excellent book! Highly recommended
