Briefly, Jimmy, a Glaswegian painter/decorator, discovers Buddhism; in the course of seeking enlightenment he rejects old habits, only to alienate his immediate family in the process.
I found the book pleasant and easy to read, and didn't mind about the dialect once I got into it. However, although I enjoyed the beginning, I soon found myself losing interest.
Whereas the two female characters, Liz (wife) and Anne-Marie (teenage daughter) are fairly well drawn, the main character, Jimmy, remains much more superficial. For instance we don't get any feel for why Buddhism is so important to him that he is prepared to give up his life with his family.
I certainly don't agree with the publishers assertion that "each character's voice has its own subtle rhythm" - actually I thought all three voices sounded exactly the same and I frequently had to look back to the start of the chapter to see which character was talking. Donovan didn't manage to create a convincing male character for me - and this means that the book lacked depth.
Further, I didn't get any new insights into Buddhism (which isn't a subject I know much about at all) - and that was disappointing. I felt that the issue Donovan really wanted to explore was the conflict between family commitment vs the self-centred (and ultimately selfish) need for self-discovery - and that Buddhism was merely a convenient vehicle to hang her theme on.
Unfortunately, because Jimmy is not clear enough as a character, she isn't able to do explore this theme particularly well - and the book becomes more of an exploration of Liz's mid-life crisis (which is portrayed much more empathetically than Jimmy's).
In summary, an interesting and enjoyable "slice of life" story, but somehow superficial.
