I had read all of Christopher Brookmyre's other books before this was realeased, and was waiting for its publish date, then after publication I came and read some other reviews which slated it as an underwhelming read ... so I went on to read something else instead.
Well, I've just finished "All Fun and Games" and found it thoroughly enjoyable ... sure it isn't full of the gut wrenching, stomach churning humour of the other books ... but once I was started on it and the story got going ... I still couldn't put it down until I'd finished it.
If you've read, and enjoyed, his other books ... have a read of this one, and don't be put off by the more critical reviews.
