“A good transition book for a middle-schooler. Easy ideas with higher vocabulary mixed in. The plot is more of a prelude to what you would expect to be the big story. Would be a good discussion-starter and could act as a gateway book to more science fiction.”
Actually, I acquired my copy about a year ago from Amazon. I remembered it from my childhood and just felt the need to reread it. I still have it. I may pass it on to one of the grandsons sometime soon.
