May I point out to the young person who complained that AMMIE, COME HOME was "too sixties" that the book was written in the sixties, and therefore should be read in the context of the late sixties. When my daughter and I read it we were into the seventies, and we both found the book fascinatingly spooky. When I reread it today, at the age of 67 (me, not the book) I still found it fascinatingly spooky.
I will admit that I prefer Barbara Mertz's "Elizabeth Peters" books more than I like her "Barbara Michaels" books, largely because despite extremely serious situations that arise in them, they are also screamingly funny, whereas the Barbara Michaels books are just screaming. But gothics--and this is a very original and unusual gothic--were all the rage then, and this is a good one.
But given what this book was trying to do, I feel that it was well done. Five stars, and don't bother to read it if you think everything older than three years ago is icky.
