I'm surprised that this short novel came from the same author as Western Wind and The Slave Dancer. In my view, the whole style of the book is very different from what I've read by Paula Fox in the past. The writing is lucid, though, and the story completely readable, so I don't think that people are likely to get bored while reading it.
James Douglas is an inner city youth who, on sudden impulse, leaves school one day in hopes of finding something "out there" for him. He's not exactly sure what he's looking for, but he has a hunch that if he's allowed to roam freely for a while then he might be able to find his mother, who disappeared a while back and left him in the care of his three aunts.
What James doesn't count on is that his relatively harmless day trip will get him entangled with a small group of outlaws who want to force him into taking all the biggest risks for their little crime operation of stealing dogs for ransom. James wants to escape and return home to his three aunts where at least he knows what's going to happen in his life on a daily basis, but breaking free of his captors isn't going to be easy. He'll have to pick his spot and make a run for it then, but there could be bad consequences if he is caught.
I have to admit that I was somewhat confused by this book. It does have its moments, though, and I wouldn't say that I dislike it. The basic concept is a good one and holds a lot of potential, and the writing flows freely enough that even the younger set of elementary-school readers shouldn't have much trouble making it to the end. If you're interested in a markedly different kind of book about life in the inner city, then perhaps you might consider How Many Miles to Babylon? as a quick summer read.
