In the mid 1980’s, I read a book at the local library. I only have vague memories of it. It was an odd story about 5 children who were “taken” from their homes. They wake up in a vehicle, and are told that some of them were given up freely by their parents and the others were kidnapped. They are renamed alphabetically by age. I believe the first kid was renamed Alex. At the end of the book, the children are given the option to return to their homes, and some decide not to.

I don’t remember any other content of this book, or the title or the author. I found the book in the children’s section of our library. Any chance you could help me find it?
