Many people have already mentioned the lack of characterization in this book and the way Boyle uses the people in this story as symbols rather than actual well rounded human beings, as well as his tendency to overwrite, describing a single event with two or more contradictory similes.
However, no has as yet discussed the fact that the depiction of Topanga Canyon in the book is a complete fabrication, leaving me to wonder if the author has ever actually been to Topanga Canyon at all. I have spent a lot of time there over the years and would like to say that there are no gated or ungated subdivisions in the actual Topanga Canyon. The Canyon community consists of individual houses, precariously built into a wild forested valley along Topanga Canyon Boulevard which winds its way for miles and miles through the Topanga mountains, alongside Topanga State Park. It would be impossible to build a housing development in this area because there is not enough flat land to do so. It is sort of like a little hippie village in the mountains. You would never know you are twenty minutes from LA there as everyone goes around in super casual comfortable clothes, unlike the characters in the novel, and rainboots because it is often muddy in all seasons except summer. The people I met in Topanga are by and large later day hippy freethinkers, older surfers, proffesors, musicians, actors, part-time pot growers and the complete opposite of the brand name and status obsessed people of the story. There are people with money there, but you would never think it by the way people act or dress and some of the cars you see around. Topanga is actually probably one of the safest and most tolerant communities in America. I didn't see any mention of Topanga Days, the Topanga Festival or the Topanga parade in the book, which is kind of like a small, better organized Woodstock, all of which are very big deals for a true Topangite or the problems of frequent rocks slides, roads washed out by mud or rain in the winter and the threat of brush fires in summer.
I realize that Boyle's aim in creating the book was to show the wide gap between the standards of living of illegal Mexican immigrants and the wealthy whites in Southern California, however his false depiction of Topanga Canyon detracts from the realism of his book and unfairly tars a wonderful community with a very nasty brush.
