I first saw The Making of Star Trek in a grocery store bookshelf as a kid, and ran to convince my mom to get it for me.![]()
I got my first copy at a book sale at my school at the end of first grade. It took me another year or two before I got around to reading the whole thing, since it was a bit rich for even a precocious reader like I was at that age. I believe I got one other Trek book at that same sale -- I thought it was the Star Trek Action Toy Book, but that didn't come out until over a year later. Maybe it was the first Blish book instead.
