Me and a couple of friends read “The Soul of a New Machine” in our teens and it was a very influential book for us. In the late 90's I found a brand new hardcover copy of the local translation in a discount bookstore and bought it with the intention of giving it as a present to one of those friends sometime later in life.
I ended up keeping the book for ~25 years and only at the time of his 50th birthday a few years ago I reckoned we're old enough now. I read the book once more and shipped it to him, literally halfway across the world. Great memories. Thank you for your work, Mr. Kidder.
