I have posted on my bookshelf the fourth book in the Ivy Malone series, Stranded.  But the ISBN is connected to a different book somehow so I had to list it without an ISBN.  Saw there are people waiting on the wish list - Help says to come here and post it, thus I am.  The book is hardcover and in great condition.  You can go to my bookshelf to request if you are looking for it.
