Andre Norton blocked out the plot for this book, but the writing was done by Jean Rabe. I have not read any other books by Norton, but I have read one other Rabe, and I have decided I just don't like her writing style. The characters irritated me, as did the use of first names in every single sentence, sometimes three times within a paragraph. No one but Horatio Cane uses names like that.
Beyond that, at the beginning I thought the plot was a simple journey tale where the characters run into trouble way more often than any normal people would, none of it really necessary. I knew plot twists were coming, but I didn't know exactly what they would be.
Perhaps a younger reader would like the book (there was no language, sex, or anything questionable), but this mature reader had to skim a lot just to finish it.
