Obviously, if you didn't like Trainspotting, chances are you're not going to like this. This is vintage Welsh: yes, more Scottish jargon; yes, more explicit sex scenes; yes, more shocking violence and yes, plenty of drugs. If the above are all part of the things you loved about whatever book you've read before, then you're going to love this one.
A more linear narrative than Trainspotting and The Acid House, with references to characters from other stories, this is a very dark and disturbing book and very, very funny. Bruce Robertson is a monster of a character and having the book mostly through his perspective can be a very frightening experience.
There are some very disturbing scenes in the book and chances are it won't be for everyone, but this is definitely one of his best books, written in another signature only-Welsh-can-do-it style (even a tapeworm has its own narrative, how tripped out is that?) he creates a magnificently complex character in Bruce with a daring twist and beautifully bleak ending.
One of his best and one I've read at least three times.
