It was almost really good. It had me gripped and really intrigued about the secrets at times but the sense of danger waned by about half way and the secrets likewise mostly didn't live up to the hype. The ending was better than I was concerned it would be though overly convoluted. It wasn't as sharp as Brookmyre's earlier books lacking his usual humour and yet not tense enough for a straight thriller either. Still I enjoyed it overall.
