This is the third in this series and, in my opinion, the grittiest. Although it can be read as a stand alone, there is so much that has gone before that, to get the best from this book, it is preferable to have read the first two.
So, Davie's world gets darker, he is drawn into more violence when revenge rears its ugly head. Despite his best effort to steer clear of the heavy stuff, to abide by his own code, circumstance, reputation and connection just keep on dragging him back. Again, the book is crammed with action, this time more violent than previous books but this is in keeping with the escalation on the streets with the prevalence of drugs and gangs so it didn't seem out of pace. It still sits a little uncomfortable rooting for a baddie, especially with what he seems to be getting involved with in this book, but he is still trying to keep the dark at bay and abide by his code so he is still worth he benefit of the doubt and, let's face it, everyone loves a bad boy!
The dialogue and language in this books is at just as high a standard as the first two, vernacular is easily worked out from context or looked up and there is some great banter between the characters. The Setting, Glasgow, is almost a character in its own right so strong the part it plays in the book, In reading the first three books, we see the degeneration of the City, How drugs, gangs and guns are becoming more widespread as time goes on.
This book is a brilliant addition to the saga of Davie McCall and I really can't wait for the next one.

I received a free copy of this book in exchange for an honest review.
