I LOVED this series when I was a kid. I searched far and wide to collect all 39 titles... I remember noticing the change in authors, and I was more than a little disappointed when I learned that the author whose writing I had enjoyed would not be the one I would be reading for the remaining 30 books, and I was downright disgruntled when I found out that the "new author" was not one person named Kathryn Kenny, but a whole variety of writers. I still read and enjoyed them all, but preferred the style and variety in Julie Campbell's first nine books. I haven't read them again as an adult, but am considering it.
I read this first book several times, and even read it aloud to my brother because I thought it was such a good story and might help him get more "into" books. Much to my dismay, he did not become a Trixie Belden fan :)
