This is the sort of book where you need to give yourself time to sit down and read without distractions. It's best enjoyed if you can get engrossed and really involved with the characters and the storyline. It took me a while to realise this, so I didn't enjoy the first half of the book as much as I did the second part.
Once I got into the story, I really enjoyed it. It kept me hanging on for the whole of the rest of the book, on edge just waiting for the finale. There were lots of twists, and just as you thought Siggy was gone for good, he reappeared again and again.
I liked the range of different characters in the book, from 'do-gooder' Dr Knox to hard-faced Mr Bray.
Dr Knox and Sutter have the most unlikely but brilliant friendship. Sutter who comes across as tough and aggressive shows his more caring side towards Dr Knox and they work so well as a team.
Overall I would give this book 3 out of 5. It's a great storyline eventually and there are some brilliant characters, however, I think it is a bit long winded in places. If you have time to give it your full attention, then it is enjoyable. If not, then it feels like a bit of an effort until you get about half way through.
