WOW. . .Just like JeffB, this was my first Science Fiction book -- At least that's what I remember but I forget now whether I read it after Tom Corbert and similar books I found in the school library. Regardless, it was the first S.F. book I bought to read. I found it about 10 years after, and I was a couple years older than, Jeff. Tho I only read it once, I've kept my paperback copy all this time. Other than that, as I remember it's an OK story and a very thin book.
