I read this during a couple of rainy lunch breaks I think - I think it was my first Wilson and maybe I was a little too old for it at the time.
I found her writing a little too simplistic at the time and the story rather unimaginative - I can't say her other stuff ever appealed to me at all.
Good for kids I suppose who have to deal with all these life problems she represents and to make them aware, but I didn't like the style of writing, I found it very bland. But again, I may have been a little above the reading age at the time. (I was about 11/12 when I read it.)
